                                 XENTIS V4.4D
                                Release Notes

        This document contains information about using XENTIS V4.4D and
        highlights features that are available in V4.4D that were not 
        available in versions prior to V4.4.  This initial section describes
        the difference between V4.4D and V4.4.  The information beyond this
        section is the standard V4.4 release notes.


A.  GENERAL INFORMATION.

        1.  V4.4D is a bug fix release.  It contains few functional
            enhancements when compared with V4.4C.  All compiled command files,
            (XCC), command files, (XCF), and pointer files created with V4.4,
            V4.4A, V4.4B, and V4.4C are compatible with V4.4D.

        2.  The problem fixed is:

            a.  Under some very complex circumstances, some calculations
                would not be performed at the time they needed to be
                performed.  The circumstance where this happened was when
                calculation A depended upon calculation B, calculation
                A was defined in multiple places, calculation A was used
                in a selection expression, calculation B was not referenced
                in the last definition of calculation A, and calculation B
                was not used in a selection expression or other calculations
                that were used in selection expressions.  In this situation
                calculation B needs to be performed before certain 
                selection expressions are performed.  There error was that
                calculation B was being performed until after selection
                expressions were being evaluated.  This problem was
                introduced in V4.4.

        3.  The new features are:

            a.  The XENTIS44_DEBUG_FLAGS logical now accepts two new debug
                flags.  These flags are designed to output to the debug
                file a copy of the records as they are being read.  The
                debug flag of A will cause Ascii characters to be output.
                The debug flag of H will cause a Hexidecimal representation
                of the bytes of the records to be output.  When Hexidecimal
                output is chosen, two lines will be output.  The first
                line is the most significant nibble, and the second line
                is the least significant nibble.

                These new debug flags only work if the R flag, if reading
                RMS files, or the Q flag, if reading SQL data, is also set.
                In addition, the user must have read access to all fields
                of all files in the report.  These flags are not operative
                in XENTIS/Update.  When SQL data is being read, only those
                fields begin retrieved will be visible.  All other fields
                will be zeros or spaces.  The output from these debug flags 
                can be extensive.  Use them with caution.

            b.  If the logical UNIFORM_CALCS is set to Y, then XENTIS will
                perform all calculations at the same time, rather than
                determining the optimal point to perform each calculation.
                Under most circumstances, performance will be degraded when
                this feature is used. Under a few circumstances, performance
                will be improved.




                                 XENTIS V4.4C
                                Release Notes

        This document contains information about using XENTIS V4.4C and
        highlights features that are available in V4.4C that were not 
        available in versions prior to V4.4.  This initial section describes
        the difference between V4.4C and V4.4.  The information beyond this
        section is the standard V4.4 release notes.


A.  GENERAL INFORMATION.

        1.  V4.4C is a bug fix release.  It contains no functional
            enhancements when compared with V4.4B.  All compiled command files,
            (XCC), command files, (XCF), and pointer files created with V4.4,
            V4.4A, and V4.4B are compatible with V4.4C.

        2.  The problems fixed are:

            a.  Under some very complex circumstances, some calculations
                would not be performed at the time they needed to be
                performed.  One circumstance where this happened was when
                calculation A depended upon calculation B, calculation
                B was defined in multiple places, the multiple definitions
                of calculation B used different files, and the last
                definition of calculation B used a lower file than other
                definitions of calculation B.  In this case calculation A
                did not get performed at the correct time.  This problem
                was introduced in V4.4.

                Another circumstance where this happened was if a
                calculation was defined more than once and the result
                of this calculation was used in a selection expression.
                Under some circumstances, only some of the calculations
                with the same name would be performed before the selection
                expression was evaluated.

            b.  When data from a data record was being printed in a report
                title, the data would sometimes be from the next record
                rather that the previous record when the first item on a
                page after the column headings was a break line rather than
                a detail line.  This problem was introduced in V4.3.

            c.  The barcode option of XENTIS is supposed to be a standard
                feature of version 4.4.  Under most circumstances, the
                software was still checking the license key for the presence
                of the barcode option.  This is wrong.




                                 XENTIS V4.4B
                                Release Notes

        This document contains information about using XENTIS V4.4B and
        highlights features that are available in V4.4B that were not 
        available in versions prior to V4.4.  This initial section describes
        the difference between V4.4B and V4.4.  The information beyond this
        section is the standard V4.4 release notes.


A.  GENERAL INFORMATION.

        1.  V4.4B is a bug fix release.  It contains no functional
            enhancements when compared with V4.4A.  All compiled command files,
            (XCC), command files, (XCF), and pointer files created with V4.4
            and V4.4A are compatible with V4.4B.

        2.  The problems fixed are:

            a.  There was a language compiler problem that would cause
                XENTIS/Edit to abort when executing under OpenVMS V7.0
                on Alpha systems.  This problem was solved by compiling
                one routine differently.

            b.  There was a language compiler problem that would cause
                two numeric values to fail an equality comparison, even
                if the numeric values were the same.  This comparison
                would fail only when the values contained fractional
                amounts.  This problem occurs only on Alpha systems.  It
                was solved by inserting additional programming statements
                into XENTIS at certain critical points.

            c.  A calculation would not be performed at the correct point
                in processing if the calculation used only literal values and
                if the SEGMENTED-SELECT setup file parameter was set to Y.




                                 XENTIS V4.4A
                                Release Notes

        This document contains information about using XENTIS V4.4A and
        highlights features that are available in V4.4A that were not 
        available in versions prior to V4.4.  This initial section describes
        the difference between V4.4A and V4.4.  The information beyond this
        section is the standard V4.4 release notes.


A.  GENERAL INFORMATION.

        1.  V4.4A is a bug fix release.  It contains few functional
            enhancements when compared with V4.4.  All compiled command files,
            (XCC), command files, (XCF), and pointer files created with V4.4
            are compatible with V4.4A.

        2.  The functional enhancements are:

            a.  V4.4A can adjust the century of date fields defined with
                particular date data types or date fields resulting from
                particular calculation functions.  The century can be
                adjusted for the TDA, MDY, DMY, and for user written date
                data types.  The adjustment for TDA, MDY, and DMY data types
                is applicable only if the length of these fields is 6 bytes.
                The century can also be adjusted for date fields created by 
                the D1, D3, and D5 functions.

                Upon initialization, XENTIS will examine the CENTURY_ADJUST
                logical.  If this logical does not exist or has a value of
                zero, "0", then no century adjustment will occur. If the
                logical has a numeric value of 1 through 99, then a century
                adjustment for the above mentioned datatypes will occur.  If
                the 2 digit year of the date field referenced is less than
                the value of the CENTURY_ADJUST logical, then XENTIS will
                place the date in the 21st century, 2000 - 2099, otherwise
                the date will be remain in the 20th century, 1900 - 1999.

                For example, suppose the field REVIEW_DATE is defined with
                the MDY datatype and contains "031502".  Normally XENTIS
                assumes this date is March 15, 1902.  If, however, the
                CENTURY_ADJUST logical has a value of 3 through 99, then
                XENTIS will use the date March 15, 2002.

        3.  The problems fixed are:

            a.  The default mask for Oracle numeric fields that were not
                defined with a precision or scale was just a minus sign.
                This problem was introduce with version 4.0.

            b.  XENTIS could not process Oracle synomyms, because the first
                two characters of field names were being overwritten with
                null characters.  This problem was introduced in V4.3 when
                Oracle7 was supported.

            c.  Oracle7 on some Alpha systems return numeric data as G-Float 
                rather than D-Float as it does on Vax.  This is resolved by 
                having sites using G-Float define the logical ORACLE_GFLOAT
                to the value of "Y".

            d.  XENTIS/File would not convert the output file from a sequential
                file to an indexed file if the MAX-FILES setup parameter was
                set to the maximum allowed, 18.  This was introduced with the
                ability of XENTIS/File to convert to indexed files in V4.3.
                XENTIS/File is now limited to 17 input files.

            e.  Break descriptions were being allowed to overlay report fields
                if the print frequency of the report field was a number.  This
                problem was introduced in V3.6.

            f.  XENTIS would not find an input file if the input file was
                specified using a search list logical, the first translation
                of the logical did not find the file, and the data dictionary
                for the file was the CDD.  This problem was introduced with
                V4.2.

            g.  The IGNORE-TIME setup parameter did not work on Alpha systems.
                This problem is solved by linking XENTIS differently.

            h.  XENTIS would fail to produce a report if a pointer file was
                used.  This problem was introduced with V4.4.





                                 XENTIS V4.4
                                Release Notes

        This document contains information about using XENTIS V4.4 and
        highlights features that are available in V4.4 that were not 
        available in versions prior to V4.4.


A.  INSTALLATION AND GENERAL INFORMATION.

        1.  If you have a previous version of XENTIS already installed
            and you never installed version 4.1 or version 4.2, we recommend
            that you copy the release notes of these previous versions
            from saveset F on your release tape and review them.  The
            following DCL command should retrieve these release notes and
            place them in your current directory:

                BACKUP/LOG tape_dev:XENTIS044.F/SELECT=[*...]*.REL*/SAVE_SET []

            where 'tape_dev' is your tape drive.

        2.  The installation procedure for V4.4 is similar to the procedure 
            used in V4.2, however V4.2 installation is quite different from 
            V4.1.  Prior to V4.2, all XENTIS images would be linked, with a 
            LINK command, while the installation procedure was executing.
            Starting with V4.2, XENTIS images are copied onto your system
            without going through a LINK step.  This results in a faster
            installation.

            This is accomplished by supplying several shareable images that
            act as stub routines for databases and other optional software
            that XENTIS supports but is not present on your system.

            In addition, the installation procedure no longer prompts the
            installer for an 'INSTALL' directory.  The 'Install' or 'Object'
            files are no longer loaded onto your system.

        3.  Starting with V4.2 XENTIS logicals are created in the SYSTEM table 
            in EXECUTIVE mode.  This is done to support the new policy of not 
            linking on the target system.  These logicals are now defined during
            system startup.  In version 4.1 and prior, the XENTIS$COMFILES
            logical was defined in the SYSTEM table in SUPERVISOR mode,
            while the XENTIS$PROGRAM, XENTIS$DEMO, and XENTIS$REPORT$DATA
            logicals were defined in the PROCESS table.  To help avoid problems
            with user written DCL command files referring to XENTISLOGICALS.COM,
            this file's name has been changed to XENTIS_LOGICALS.COM, and
            XENTISLOGICALS.COM will still exist but contain only comments.

        4.  In response to customer demand, multiple versions of XENTIS may
            be installed and active at the same time.  Please see section
            below for more information.

        5.  Beginning with V4.2, the XENTIS startup procedure defines a number 
            of additional logicals.  These logicals define which optional parts 
            of XENTIS are available on your system, and which ones will have to 
            use stub routines. The definition of these logicals are found in
            the XENTIS_SHARE_LOGICALS.COM file.

        6.  An additional system DCL command file is supplied for the
            purposes of shutting down XENTIS.  This command file is called
            XENTIS_SHUTDOWN.COM and can be found in the XENTIS44$COMFILES:
            directory.  This command file removes the system logicals that
            were created with the XENTIS44_START.COM file.  It will also
            remove the XENTIS images if they were installed with the
            INSTALL command. (This does not delete any files from disk.)  It
            is recommended that the XENTIS_SHUTDOWN.COM procedure be called
            from the system shutdown procedure, SYS$MANAGER:SYSHUTDWN.COM.

        7.  The user pack routine, used for user written data types, is
            implemented as a shareable image beginning with V4.2.  This 
            allows you to write and test your routine without having to 
            relink XENTIS every time.  Linking instructions are found in 
            the sample source code, XUUSER_PACK.BAS.  In addition, the 
            number of parameters for this routine has changed.  Please 
            review the sample source code for further information.  This
            information represents no change from V4.2, however the
            name of the shareable image is now XENTIS44_USER_PACK.EXE.

        8.  On VAX systems XENTIS V4.4 requires OpenVMS V5.0 at a minimum.  
            Installation and operations has been tested on a OpenVMS V5.2 
            system, but it has not been tested on a OpenVMS V5.0 or V5.1 
            system.  As result we recommend that users be running at least 
            OpenVMS V5.2.

            On Alpha AXP systems XENTIS V4.4 requires OpenVMS V6.1 or later.

        9.  If an additional cpu is licensed, and that system has a different
            database configuration, it is not necessary to relink XENTIS.
            The XENTIS startup procedure effective with V4.2, which must be 
            run on every node licensed for XENTIS, will detect the different
            database configuration and define the XENTIS logicals 
            appropriate for each licensed CPU.

        10. The circumstances where XENTIS needs to be relinked are now quite
            rare.  Therefore, object libraries are no longer included on the
            distribution tape.

        11. Beginning with V4.2, CALLABLE XENTIS is a feature that is 
            available only upon request from your vendor.  It is no longer
            available in the standard release.  CALLABLE XENTIS provides the 
            ability for a 3GL program to call XENTIS (except /Dictionary and 
            /Edit) in the context of the same process or image.  XENTIS can 
            still be executed in the context of a subprocess.  Using XENTIS 
            in a subprocess is not considered CALLABLE XENTIS.

        12. When the XENTIS44$SUPPORT logical is set to a value of Y, then
            whenever XENTIS/Report ( or /File, /Word, /Model, /Creport, 
            /Update) writes a XENTIS Command File, .XCF, it will write
            into the file considerable information regarding the report,
            the data files, the setup file, and its operating environment.
            This information can be very valuable for the customer support
            staff in diagnosing problems with a particular report.  When
            sending an XCF file to the customer support department, please
            set this logical to a value of Y before creating the XCF file.
            This feature became effective with version 4.1.

        13. If you are upgrading from V4.2 or prior, please note that the
            names of the user modifiable shareable images have changed. 
            Their previous and current names are as follows:

                XENTIS_USER_PACK.EXE          XENTIS44_USER_PACK.EXE
                XENTIS_USER_FUNCTION.EXE      XENTIS44_USER_FUNCTION.EXE
                XENTIS_XRP3GL.EXE             XENTIS44_XRP3GL.EXE

            The application program interface (API) to these routines have
            not changed from V4.2.

        16. The Alpha AXP version of XENTIS has not been tested with CDD,
            although it is likely that it will work.  The Alpha AXP version
            does not work with Ingres, Sybase, or Oracle.  Contact your
            vendor regarding more information on these databases.  The Rdb 
            interface has been tested and is supported.


 B.  INSTALLING AND USING TWO DIFFERENT VERSIONS AT THE SAME TIME

        Beginning with version 4.3 XENTIS allows two or more different versions
        to be installed and active at the same time.  This is accomplished
        by including the version number, in this case 44, with the logicals
        used by XENTIS and including the version number in many executable
        files.  The information in this section describes how this is
        accomplished and what the customer needs to do to insure smooth
        operation of two or more versions at the same time.

        1.  All XENTIS logicals that previously began with XENTIS, now
            begin with XENTISnn, where 'nn' is the version number.  Please
            note that symbols such as XENTIS$DICT and XENTIS$PASSWD have
            not changed.  These symbols are unique to your process and do
            not need to be changed.

        2.  All XENTIS executable files that may get installed with the INSTALL
            utility now have the version number appended to the filename.
            This is because the INSTALL utility does not allow two or more
            files with the same name to be installed at the same time.
            Customers that have a limited user count license, or those that
            have a Progress database interface license must either install
            XENTIS executables with the SYSLCK privilege or must give each
            user the SYSLCK privilege.  (The XENTIS startup procedure
            automatically examines the XENTIS license for these two conditions
            and installs the executables if appropriate.)  Please note that
            due to a bug in Rdb, the XENTIS executables should not be 
            installed if the Rdb interface is to be used.

        3.  None of the control files or data files that XENTIS uses have had
            their names modified for this purpose.  The lone exception to
            this rule is the startup file that is executed during system
            startup.  Its name is now XENTISnn_START.COM, found in the
            SYS$MANAGER directory, where 'nn' is the version number.

        4.  XENTIS version 4.4 may be installed and started, while a
            previous version is active and running.  It may not be installed
            while another installation of V4.4 is active and started.  The
            V4.4 installation procedure detects this condition and will
            halt its processing.

        5.  During system startup, the various versions of XENTIS should be
            started in order with the oldest version first and the newest
            version last.  When shutting down XENTIS, it is best if the
            reverse order is followed; the latest version first.

        6.  Existing batch command files present a unique problem.  Many or
            most batch command files created prior to version 4.3 contain a 
            line in them similar to "RUN XENTIS$PROGRAM:XRP". Under the old 
            scheme of filenames and logicals, this would always execute the 
            current version of XENTIS.  Under the new scheme of filename and 
            logicals, this would execute the version of XENTIS that was 
            previously installed.  

            If it is desired for pre V4.3 batch command files to use version 
            4.4, then perform the following steps.

            a.  Copy XRP44.EXE to XRP.EXE in the same directory.
            b.  Define a logical as:  DEFINE XENTIS$PROGRAM XENTIS44$PROGRAM

            Beginning with batch command files created under version 4.3 or 
            later, you can control which version of XENTIS is used.  This is
            done with the XEN_VER DCL symbol.  To use version 4.3, set XEN_VER
            to "43"; to use version 4.4, set XEN_VER to "44"; etc.  This
            symbol can be set in a user login file or the system login file,
            SYS$MANAGER:SYLOGIN.COM.  If this symbol is not set, the current
            version will be used.

        7.  To remove an older version of XENTIS from your system,
            execute the XENTIS_SHUTDOWN.COM procedure for all versions
            in the order of most recent version first. (XENTIS_SHUTDOWN.COM
            was introduced in version 4.2.)  Next, delete all the files
            from the older version.  Next deassign the PKMSSHR logical.
            Next, execute the XENTIS startup files, found in SYS$MANAGER, 
            in the order of most recent version last.


 C.  NEW FEATURES


        1.  /Report and /Report modules (/File, /Word, /Model, /Update).

            a.  XENTIS now supports a debug mode of operation.  When operating
                in debug mode XENTIS will print detailed information to
                indicate what it is doing along each step of the way.  The
                logical XENTIS44_DEBUG_FLAGS controls whether or not XENTIS 
                operates in debug mode and what data is printed.

                Utilizing this feature is very beneficial in diagnosing
                reports where no records are selected, where too many records
                are selected, where calculation results are different than
                expected, and other similar problems.

                The following table documents what data is printed when the
                appropriate debug flag is set.

                   Debug Flag   Debug data printed
                   ----------   -----------------------------------------
                        C       Calculations Expressions
                        D       Dictionary Operations 
                        E       Calculation Detail Operations
                        F       Data File Opens and Closes
                        Q       SQL Operations
                        R       Data File Reads
                        S       Selection Expressions
                        T       Selection Detail Operations
                        W       Data File Writes

                For example, to print debug information about file read,
                selection expressions, and calculations; define the debug
                logical as follows:

                        $DEFINE  XENTIS44_DEBUG_FLAGS  RSC

            b.  It is possible to direct the output of debugging statements
                to a file rather than the user's terminal.  This is done by
                defining the XENTIS44_DEBUG_OUTPUT logical to translate to
                a file.  For example, to cause all debug output to go to a
                file named REPORT_DEBUG.LIS then enter the following before
                executing XENTIS:

                        $DEFINE  XENTIS44_DEBUG_OUTPUT  REPORT_DEBUG.LIS

            c.  XENTIS now supports writing audit records to a history audit
                file.  The name of this history file is controlled by the
                new HISTORY-FILE setup file parameter.  This file has the
                following record layout:

                   Field Name             Data Type        Field Size
                   ----------------       ---------        ----------
                   User_Name              T   Text               12
                   Terminal               T   Text                8
                   Node_Name              T   Text                6
                   Function               T   Text               10
                   Process_ID             L   Long                4
                   UIC_Member             W   Word                2
                   UIC_Group              W   Word                2
                   Start_Time             DA  VMS Date            8
                   End_Time               DA  VMS Date            8
                   CPU_Used               L   Long                4
                   Page_Faults            L   Long                4
                   Direct_IO              L   Long                4
                   Buffer_IO              L   Long                4
                   Select_Count           L   Long                4
                   Primary_Count          W   Word                4
                   File_Count             W   Word                4
                   File_Names             CT2 Text              500

                The history file is similar to, but different than, the
                registry file that was introduced in version 4.3.  The 
                registry file records which XCF files are being used, and 
                a single report may reference several XCF files.  The 
                history file is designed to track who is using XENTIS, 
                how much system resource is being used, and what data is 
                being accessed.

                The statistics recorded in this history file will be
                different from the statistics displayed on your terminal.
                The statistics written to the history file are gathered from
                a point in time shortly after XENTIS is invoked, until a
                time shortly before XENTIS is exited.  The statistics
                displayed on the user's terminal are gathered from a point
                shortly after the "Executing..." message is displayed.

                A temporary dictionary file is included in the XENTIS data
                directory that describes the history file.  This will allow
                you to produce reports using the history file.

                To not use this feature set the parameter value to spaces
                within quotes.

                A description of each field in the history file is as follows:

                User_Name     -- The OpenVMS user name.
                Terminal      -- The name of the terminal where XENTIS was
                                 used.  If used in batch, this field will be 
                                 blank.
                Node_Name     -- The Decnet node name.
                Function      -- The XENTIS function(REPORT, UPDATE, etc) used.
                Process_ID    -- The OpenVMS process Id (PID).
                UIC_Member    -- The member part of the process' UIC.
                UIC_Group     -- The group part of the process' UIC.
                Start_Time    -- The date and time XENTIS was started.
                End_Time      -- The date and time XENTIS completed.
                CPU_Used      -- The amount of CPU used between the start time
                                 and the end time, measured in 1/100 second.    
                Page_Faults   -- The number of page faults recorded between the
                                 start time and the end time.
                Direct_IO     -- The amount of direct I/O recorded between the
                                 start time and the end time.
                Buffer_IO     -- The amount of buffered I/O recorded between
                                 the start time and the end time.
                Select_Count  -- The number of records selected.
                Primary_Count -- The number of primary data files used.
                File_Count    -- The number of data files used, not including
                                 the extra primary files.
                File_Names    -- A list of filenames delimited by the pound (#)
                                 character, where the first name is the XCF 
                                 filename, followed by the data file names.  
                                 This field is variable in length.

            d.  The calculation and selection processing routines have been
                rewritten.  In previous versions, all calculations were 
                performed on every selected detail, and all selection
                expressions were performed at the same time.  Calculations 
                and selections are now performed only when needed. 

                To support the rewrite of the record selection logic routine
                the SEGMENTED-SELECT setup file parameter has been added.
                To use the rewritten routine set this parameter value to Y.
                To execute selection logic the way it existed prior to V4.4
                set this parameter value to N.  The default value is shipped
                as Y.  To view selection logic as it is being executed
                use the debug feature documented elsewhere in these release
                notes.

                This rewrite of selection logic may yield substantial
                performance increases in situations where the report reads
                data from multiple files, the selection logic references
                data from multiple files, and a small number of records
                are being selected.  Some reports may yield a 70% or more
                decrease in CPU usage.  

                There are also some circumstances where a report will 
                take slightly longer to execute.  This situation involves
                reports where records are rejected due to missing data in
                auxiliary files rather than data that fails to match the
                selection criteria.

            e.  XENTIS/Report now support some selection on subtotals.
                To activate this feature you must respond with an S at the
                "Do you wish to have breaks" prompt.  When this this feature
                is used, each break field will prompt the user for a
                series of select-on-subtotal expressions.  All expressions
                must evalute to TRUE for the group of records to be selected.

                Each expression must be of the form:   
                        Accum-fld  Operator  Numeric-literal.

                "Accum-fld" must be a field specified in the report that is
                is accumulated, but not using running totals or alternate
                accumulation types such as /AVE, /MIN, etc.  "Operator"
                must be a XENTIS comparison operator.  "Numeric-literal"
                must be a valid XENTIS numeric literal.

                For example, if you a accumulating a field called ORDER_AMOUNT
                and you wish to select those records whose accumulate order
                amount is greater than 1000, then you would enter the
                following expression.
                        ORDER_AMOUNT > 1000.0

            f.  The QUOTES-AROUND-STRINGS parameter in the Model Control
                File has been enhanced to accept a value of C.  The value
                will instruct XENTIS/Model to put quotes around the data
                (text, numeric, and datetime) only if the data contains
                a comma (,) character.  In addition, if the data contains
                quotes, then the quotes will be doubled and the data will
                be surrounded by quotes.

            g.  Two additional Model Control files have been added to the
                set of supplied control files, TAB_SEPARATED.DAT and
                COMMA_SEPARATED.DAT.  Their names are self explanatory.

            h.  The TABLE, MEMBR, and ELEM calculation functions now
                accept tab as a delimiting character.  This is useful
                for importing tab delimited data.  To use a tab character
                in display mode enter the following calculation:
                        TAB;1 = CHR(9)
                and then use the TAB calculation field.

            i.  The output format of the DIR command has been improved.

            j.  The new setup file parameter PROMPT-LIT-INPUT controls
                whether prompted literal prompt the user on SYS$INPUT: or
                on SYS$COMMAND:.  This parameter only accepts values of
                "I" or "C".  The default value shipped with V4.4 is "I".
                Changing it to "C" may be beneficial for executing XENTIS
                within DCL command procedures.

            k.  To improve the security of data files used with the temporary
                dictionary feature, the setup file parameters TEMP-DROP-PRIV
                ALLOW-TEMP-UPDATE have been added.  If your site installs 
                XENTIS with privileges and the TEMP-DROP-PRIV parameter has a 
                value of Y, then XENTIS will drop its privileges whenever it 
                accesses a data file that is described by a temporary 
                dictionary.  Please remember that the dictionary file must 
                reside in the same directory as the data file.  The
                ALLOW-TEMP-UPDATE parameter has valid values of Y or N only,
                and controls whether or not XENTIS/Update can be used with
                a file that is described by a temporary dictionary.  The
                default value shipped for TEMP-DROP-PRIV is Y, and the default
                value shipped for ALLOW-TEMP-UPDATE is N.

            l.  XENTIS now offers an additional method for determining how
                ISAM files are joined.  XENTIS will now access a Join
                Suggestion file prior to the Key Section in the dialogue.
                The Join Suggestion file is a text file that contains the
                dialogue responses for the Key Section prompts that join
                two ISAM files.  The name of the Join Suggestion file is
                a combination of the parent and child filenames with an
                underscore (_) between the parent and child and a 
                .JOIN file type (extension), such as PARENT_CHILD.JOIN.
                The directory where the Join Suggestion file is located
                is controlled by the JOIN-SUGGEST-LOC setup file parameter.
                The default value as shipped for this parameter is
                XENTIS44$JOIN:, which is a logical the user needs to define.

                For example, suppose there are two ISAM files, ORDHEAD and
                ORDDETAIL, whose fieldnames are not consistent with each
                other.  Until V4.4, XENTIS could not make an intelligent
                guess as to how these files should be joined.  Now with
                a Join Suggestion file, XENTIS can join these two files
                using the information in the Join Suggestion file.  This
                file should be named ORDHEAD_ORDDETAIL.JOIN and located
                in the directory specified by the JOIN-SUGGEST-LOC setup
                file parameter.  The ORDHEAD_ORDDETAIL.JOIN file might
                have the following contents:

                        2               !Key to access file by
                        CUSTOMER_NUMBER !First field to build key
                        ORDER_NUMBER    !Second field to build key
                        NONE            !No more fields to use
                        Y               !Key has multiple records
                        N               !Don't replace missing recs with zeros

            m.  The setup file parameter FLOAT-LEFT-PAREN now controls
                whether or not the left parenthesis floats to the right
                when the 'surrounding parenthesis for negative numbers'
                feature is used.  To maintain compatability with prior
                versions, the default value shipped is N.  The allowed
                values for this parameter is Y and N.

            n.  XENTIS version 4.4 provides a number of new functions that
                can be used in calculations.  They are:

                1.  HEXN.  This function converts a number into a long
                    integer and then into its hexadecimal representation.
                    This function has one argument, a number field.  The
                    result of this function is always an 8 character text
                    field.

                2.  HEXT.  This function converts a text field into its
                    hexadecimal representation.  It has one argument, a
                    text field.  The result of this function will be a
                    text field whose length is twice that of the argument.

                3.  CURDT.  This function retrieves the current date and
                    time from the operating system.  It has one argument,
                    a text field or a number field.  The result is a datetime
                    field.  The argument serves only to control the frequency
                    of the execution of the calculation.

                    To retrieve the date and time from the operating system
                    every time a new record is read from the primary file,
                    you would enter the following calculation:
                        CURDATE = CURDT(#A1)
                    assuming that the first field in file A is either a text
                    field or a number field.

                4.  INCR.  This function provides an increment capability
                    to XENTIS.  It uses three arguments.  The first argument
                    is a number field indicating the initial value of the
                    result. The second argument is a number field indicating
                    the increment value.  The third argument is a number field
                    or a text field that serves to control the frequency of
                    it execution.

                    For example, if I wished to create tag numbers that start
                    at 1500 and increase by 10 for each record in the customer
                    file, I would enter the following calculation expression.
                        TAGNUM = INCR(1500, 10, A:CUSTOMER_NAME)

                    Please note that all calculations are performed prior to
                    sorting.

                5.  CVTN, CVTD, and CVTT.  These three functions do data type
                    conversions of data that you do not have control over
                    their defined data type.  These functions take two
                    arguments.  The first argument is a text field containing
                    the data that you wish to convert.  The data type of this
                    argument can be any text class type.  The second argument
                    is a text field containing the data type abbreviation
                    as specified in the reference manual appendix regarding
                    data types.  The only difference between these functions
                    is the resultant data type.  CVTN returns a numeric field,
                    CVTD returns a datetime field, and CVTT returns a text
                    field.

                    For example, suppose you have a 120 byte field named
                    FILLER whose data type is STR or T.  You know that in
                    bytes 21 and 22 is an unsigned word integer that you
                    want to process.  This data can be accessed by using
                    the following calculation:
                        CODE = CVTN( SEG( C:FILLER, 21, 22), "WU")

                    In another example suppose characters 7 though 12 
                    of an Order Number field contain the date of the order
                    in DDMMYY format.  This data can be accessed by using
                    the following calculation:
                        ORDER_DATE = CVTD( SEG( B:ORDER_NUMB, 7, 12), "DMY")

                6.  SUBSA and SUBS1.  These two functions perform character
                    substitutions in a text field.  These functions take
                    three text arguments.  The first argument is the text
                    field that is to modified.  The second argument is the
                    search text field.  The third argument is the replacement
                    text field.  The difference between SUBSA and SUBS1 is
                    that SUBSA performs the character substitution on all
                    occurrences of the search field that are found, while
                    SUBS1 performs only one substitution.  The second and
                    third arguments may be different lengths.

                    For example, to substitute all commas with a dashes in
                    a credit memo field, you might use the following
                    calculation:
                        NEW_MEMO;12 = SUBSA(B:CREDIT_MEMO_NUM,",","-")

            o.  XENTIS now provides support for Comma Separated Value
                files and for Tab Separated Value files, CSV and TSV
                respectively.  This makes importing data from an external
                source much easier.

                To use a CSV or a TSV file you must describe the imported
                data in either a XENTIS dictionary or in a Temporary 
                dictionary.  When using a Temporary dictionary you will need
                to add a "RECORD_FORMAT: C" line for a CSV file or a
                "RECORD_FORMAT: T" line for a TSV file to your Temporary
                dictionary file.  When using a XENTIS dictionary you should
                respond with either a C or a T at the "Record Format" prompt.

                When using a CSV or TSV file, only a few data types are
                valid.  The available data types are T, ZT, STR, and YN for
                text fields, GN for numeric fields, and TDA, MDY, DMY, and
                PRD for date fields.

                When defining fields for a CSV or TSV file be sure to specify
                a field length that will be large enough for the largest
                instance of the field.

            p.  There is a new setup file parameter called RIGHT-MARGIN.
                This parameter controls the right margin which determines
                where certain elements of the title lines are printed.  A
                value of zero indicates that XENTIS should duplicate its
                behavior prior to V4.4.  The default value is shipped as zero.
                This parameter also affects the SPREAD command and the DUMP
                command.

            q.  There is a new setup file parameter called STATS-ON-REPORT.
                This parameter controls whether or not performance statistics
                are printed on the bottom of the report.  The valid values
                for this parameter are Y and N.  The default value as shipped
                is N.

            r.  XENTIS V4.4 now supports the GOTO NEXT command, the F17 key,
                and the PF1-PF4 key combination, in the Format Section of 
                the dialogue.

            s.  The error handling has been improved.  Most occurrences of
                invalid floating point data will now be processed without
                aborting.  Most circumstances where XENTIS needs to abort
                will now result in the setting of the DCL $STATUS symbol
                to an abort error code.  This will allow DCL command files
                to trap for fatal aborts.

            t.  The maximum number of literals allowed has been increased
                to 200.

            u.  There is a new setup file parameter, UPDATE-LOG-NAME, that
                controls the name of the log file for XENTIS/Update.  If
                the parameter value contains percent-X-percent, %X%, then
                this sequence is replaced with the current date and
                time with the format used in previous versions.  If the 
                parameter value contains percent-C-percent, %C%, then this 
                sequence is replaced with the current XENTIS Command File 
                name.  If the parameter value contains percent-D-percent,
                %D%, then this sequence is replaced with 8 numeric characters
                that indicate the current date.  If the parameter value
                contains percent-T-percent, %T%, then this sequence is
                replaced with 6 numeric characters that indicate the current
                time.  The default value of this parameter is
                SYS$DISK:[]UPDATE_LOG_%D%_%T%.LIS.

            v.  XENTIS now allows the user to respond with multiple ranges for
                the "First key to read" and "Last key to read" prompts for
                the primary file.  This is done by entering multiple ranges
                at the prompts with each range separated by the delimited
                specified by the FIRST-KEY-RANGE-DEL setup file parameter.
                The default parameter value is a semicolon, (;).

                This new capability may be used with the multiple segment
                feature for first/last key to read that was introduced in
                version 4.3.

                For example, if reading the customer file using the customer
                name index and you wish to access all customer's whose name
                begins and end with A, C, E, or G, you would respond as
                follows at both the "First key to read" and "Last key to
                read" prompts:

                        First key to read? A;C;E;G
                        Last key to read? A;C;E;G

                If more than one range is specified for the First Key then
                an identical number of ranges must be specified for the
                last key.


            w.  The Sort-On-Total feature is now available for XENTIS/File.
                Its usage is the same as in XENTIS/Report or XENTIS/Model.

            x.  Pressing CTRL/C while XENTIS is in its selection phase will
                under many circumstances exit the selection phase and proceed
                on to the sort and print phases.  This is not guaranteed to
                work this way under all cases.

            y.  The following Sybase datatypes are partially supported:
                binary, varbinary, image, and text.  The first three are
                converted to a XENTIS STR datatype with a maximum length
                of 512 bytes.  The text datatype is converted to a XENTIS NT
                datatype with a maximum length of 512 bytes.

            z.  Temporary dictionaries now support the FIELD_POSITION,
                FIELD_OCCURS, FIELD_STRIDE, and RECORD_FORMAT labels.  The
                definition of these items are the same as in XENTIS/Dictionary.

        2.  /Edit

                No enhancements specific to XENTIS/Edit were made for
                version 4.4

        3. /Dictionary

                No enhancements specific to XENTIS/Dictionary were made 
                for version 4.4.

        4.  General Enhancements

            a.  The Barcode module is now part of the standard XENTIS product.
                It is no longer an extra cost module.

            b.  Due to a lack of usage, DBMS and Adabas/Natural database
                support has been removed from the software.  MCBA Dibol
                and GSI'S FMS-Isam support has also been removed for similar
                reasons.  This significantly reduces the size of the 
                executable images.

            c.  For MAXCIM users, XENTIS now allows the usage of the NCA Byte
                Array, XENTIS datatype NBY, fields.  These fields will be
                treated identical to text fields whose datatype is STR.
                XENTIS will not alter or convert any byte of these fields.
                The real datatype of the data that is stored in these fields
                is unknown to XENTIS, and varies from file to file and program
                to program.  It is the user's responsibility to know the
                real datatype of an NBY field.  In many cases the data 
                contained in these fields is of a binary nature and is not 
                printable.  You will probably need to use the new CVTN, CVTD, 
                or the CVTT functions on a segment of the data contained in 
                one of these fields.

                For example, suppose the STATUS_FLAG_ARRAY is a set of long
                integers, which are 4 bytes long, that contain some status 
                flags.  To use the third status flag you will need enter a 
                calculation as follows:

                STATUS_FLAG_3 = CVTN(SEG(STATUS_FLAG_ARRAY,9,12),"L")

                This calculation says the following:  Use the SEG function
                to extract bytes 9 through 12 from STATUS_FLAG_ARRAY, then 
                use these four bytes as if they are a long integer, and place 
                the result into STATUS_FLAG_3.

            d.  For MAXCIM users, in save set F on the distribution tape are
                two files, ECBFILE.DMP, and ECBFILE.XCF.  The ECBFILE.DMP
                describes the MAXCIM ECB file, and can be loaded into a
                XENTIS dictionary using the Dictionary Load utility.  This
                file can also be used as a XENTIS Temporary Dictionary if it
                is placed in the same directory as the MAXCIM ECB file and
                given a Temporary Dictionary file extension.  The ECBFILE.XCF
                file is a XENTIS Command File that produces a report
                describing your MAXCIM ECB file.  To use this XCF file with
                a Temporary Dictionary you need to define a logical ECBFILE 
                that translates to your desired MAXCIM ECB dictionary file.

                While these files are not supported, they provide a good
                example of some of the newer and more advanced features of
                XENTIS.

            e.  The RDA and the RDR datatypes may now be either 2 bytes or
                4 bytes in length.

            f.  The General Numeric (GN) datatype now allows comma (,)
                characters and dollar ($) characters as part of the data.
                These characters will be ignored.  This is useful if your
                input file is a comma separated values file (CSV) or a tab
                separated values file (TSV).

            g.  The following data types are now supported on Alpha AXP
                systems only:

                Data type                               Abbr    Size
                -----------------------------------     ----    ----
                IEEE Single Precision Floating           FS       4
                IEEE Double Precision Floating           FT       8
                IEEE Extended Precision Floating         FX      16

                You may define a field in a XENTIS dictionary using
                these data types, however, if you should attempt to use
                them on a VAX system, you will read and write a value of
                zero.


 D.  KNOWN PROBLEMS AND RESTRICTIONS

        XENTIS has several known problems and restrictions.  Some of these
        are known bugs in the XENTIS software, some are known bugs in
        other software that XENTIS uses, such as Rdb, while others are
        limitations placed upon XENTIS by the operating system.

        1.  Print frequency U (for Unique) and the setup parameter
            ACCUM-IF-UNIQUE may not always work when multiple primary files
            are being used.  This is because two records in different primary
            files may have the same record pointer (RFA in RMS files).  After
            sorting, these two records may get sorted next to each other.  As
            a result, XENTIS thinks they are the same record, because they
            have the same RFA.

        2.  If the user enters a prompted literal, then backs up and makes
            a correction to the prompted literal, the user may be
            prompted for the first literal even though it is no longer part
            of the report.  This happens because literals that were entered
            and then changed during the report definition, remain in the
            internal literal pool.  This problem will automatically
            disappear when the report definition is saved and the report is
            reexecuted after exiting.

        3.  A problem may occur with XENTIS Dictionaries created prior to
            XENTIS V3.1.  In some cases the prefix entry in the file
            record was not created correctly.  Due to enhancements made to
            the processing of prefixes, the incorrect data stored in such
            prefixes may cause reports or /Edit to work incorrectly.  This
            problem is resolved by running "Edit a Data Dictionary" from the
            XENTIS/Dictionary menu and selecting "Change" "File" followed
            by changing the prefix value from spaces to null.  Running the
            program XDFIX_PREFIX found the the images directory will also
            correct this problem.

        4.  The sizes of all records from all input files, plus calculations,
            sort records, and literals, cannot exceed 32767 bytes.  Under
            most circumstances this restriction is not a problem.  However,
            should this limitation be reached, it is possible to avoid the
            limitation by restricting the record size of certain files.  This
            is accomplished as the following example illustrates.
                $ DEFINE RECSIZE_LIMIT_SALESHIS 12000
            If the above DCL command is entered, then XENTIS will limit the
            SALESHIS file to 12000 bytes.

        5.  /Update does not allow the same data file to be used twice,
            unless those files are used only to perform selection and/or
            calculations.  This means that you cannot modify a field or
            delete a record if that field or record is located in a file that
            is used two or more times in a single /Update run.  This
            restriction is placed due to problems involving record locking,
            rereading records by RFA, and RMS not being able to keep track of
            where the next record is located.  This restriction may cause
            certain existing XENTIS command files to no longer work;
            receiving the error message "Same physical file update not
            allowed".  These XENTIS command files may not have been working
            correctly.  The solution to this problem is to perform this
            operation in two passes; the first being a SELECT function where
            the desired records are selected and their pointers are saved
            into a pointer file, followed by a REUPDATE where the selected
            records are read after retrieving their pointers from the pointer
            file. This restriction was effective with V3.6 of XENTIS.

        6.  When using a MAXCIM ECB data dictionary, only one version of a
            data file is allowed.  Specifying a version other than the most
            current version will be ignored.  Using the ACTUAL/GENERIC syntax
            does not get around this restriction.  The LIST FILES command
            displays the filename as the user entered the filename, which
            will be different from the file that will be used if a version
            other than the most current version is entered by the user.

        7.  The DROP-PRIV setup file parameter has no effect with MAXCIM
            V4 or later files.  This is to conform to the MAXCIM security 
            mechanism.

        8.  Calculations-on-totals should not use more than one occurrence
            of the same data field in the same report.  An easy work around
            is to specify a calculation such as:  AMOUNT3 = AMOUNT(3)

        9.  There is no support in the software for descending keys.  They
            may, however, work under certain limited circumstances where
            the ascending/descending nature of the key is not used.

        10. Entering a print mask using dual leading dollar signs or dual
            leading asterisks without including a trailing minus sign is
            accepted.  Printing negative data will thus erroneously print
            as if it were positive, with no error indicated.

        11. The COBOL to XENTIS dictionary transfer does not support sequence
            numbers in columns 73 through 80.  Sequence numbers are typically
            used in older punched card source files.

        12. The Rdb interface converts Rdb VARCHAR fields to CHAR fields.  This
            means that VARCHAR fields will have spaces appended to the end of
            the field to fill out the field to its maximum size allowed.  If
            a VARCHAR field is used in an index, which is usually not wise,
            and two or more tables are joined using the /NOSQL qualifier, then
            you will probably have to specify a sub-field as your 'field to
            build key' field.  For example: if the desired index to file B is
            using datatype VARCHAR(5) but only two of the five characters are
            really being used, then you should use only the first two
            characters of the input field from file A.

        13. When displaying the output of a report to the screen, there is
            a limit of the number of lines available.  If a detail contains
            more than the limit, then one or more printed lines may scroll
            of the top of the screen.

        14. The FMTNM function does not support the blank-when-zero feature
            of print masks, designated by the ampersand character, the
            trailing DB if negative feature, the trailing CR if negative
            feature, or the surrounding parenthesis if negative feature.

        15. The minimum version of Ingres that is supported is version
            6.3.  This allows XENTIS to support groupids of the
            Knowledge Management Extension to Ingres.

        16. The Rdb interface does not support the catalog and schema
            features of Rdb V4.1 and later.  When XENTIS/Report attaches
            to a multischema database it specifies that the multischema
            capability will be turned off for the duration of the
            attachment.  If a multischema database is used, the then the
            RDB-USE-ATTACH setup parameter must be set to Y.

        17. When entering a CDD pathname and you do not want CDD$DEFAULT
            applied, be sure to start the pathname with _CDD$TOP rather
            than CDD$TOP.  In other words, start the pathname with an
            underscore character.

        18. XENTIS/File does not work when the output file is an Rdb table
            and the table contains computed_by fields, or virtual fields.

        19. Calculation expressions may not include the vertical bar
            character (|).  If you need a vertical bar character, the
            following calculation expression will yield one:
                BAR;1 = CHR(124.)

        20. Due to a bug in Rdb, the Rdb interface for XENTIS does not work
            if XENTIS is installed with privileges.  If you have a limited
            user license key, give all XENTIS users the SYSLCK privilege
            and define the XENTIS44_PRIV_LIST to NOINSTALL before executing
            the XENTIS startup procedure (SYS$MANAGER:XENTIS44_START.COM).

        21. The minimum supported version of Rdb is version 4.0 on Vax systems
            and 6.0 on Alpha AXP systems.

        22. The minimum supported version of Oracle is version 7.0. To use
            Oracle7 on Alpha AXP systems contact your XENTIS vendor.

        23. The only supported versions of Progress are 6.2N and 6.2L.

        24. The Info File Creation program does not work with Rdb V4.0, but
            it does work with later versions of Rdb.

        25. While XENTIS is supported on OpenVMS V6.1 for Alpha systems,
            because of various RTL bugs we recommend that V6.2 or later
            be used.


 E.  PROBLEMS FIXED IN XENTIS V4.4.

        1.  XENTIS/Dictionary erroneously allowed the user to define a file
            with an index comprised of integers and text fields.  RMS does
            not allow an index with multiple segments if one of the segments
            is an integer or a date.  This problem has existed since version
            2.0.

        2.  The EXCEPTIONS-FILE and REGISTRY-FILE setup parameters could not
            be changed online with the SET command.  This problem was
            introduced with these particular setup parameters.

        3.  The INSERT command did not work in the break section of the
            dialogue. It would delete all the breaks.  This problem was
            introduced in V3.6.

        4.  If print attributes are used with title lines and the attributes
            flag, /ATTR=, was entered in lower case, then the attributes flag
            and the attribute name were displayed on the screen when using
            display mode.  The report output did not have this problem. This
            problem was introduced in V4.1.

        5.  There were several instances, including using the SELECT function,
            where XENTIS would not prompt the user to press the return key
            when the program was completing and about to exit.  XENTIS should
            now issue the prompt whenever it is exiting, unless the user has
            specifically requested the exit.

        6.  XENTIS would abort when using the LIST command if the LIST output
            was directed to a file whose name was not valid.  This problem
            was introduced in V4.1.

        7.  If your first N files are from an SQL database, your N+1 file
            is an RMS file, you were joining your RMS file using a field
            from file 2 to N, and your join field was not used elsewhere
            in the report, then the RMS file would not get joined to the
            SQL files.

        8.  The SQL-SORT parameter would be ignored if the sort fields for
            an SQL database report were numeric or date.

        9.  If the CONVERT-SEGMENTS setup parameter was set to Y and a
            relative file was used as an auxiliary file, then under some
            circumstances the user would get the 'Key Segment Mismatch' error
            message.

        10. XENTIS/Model would output a grand total line when only detail
            output was requested.  This problem was introduced in V4.3 and
            has been corrected.

        11. In display mode with several hundred fields, XENTIS/Report would
            sometimes go into an infinite loop at the very first
            "field name/number/literal" prompt if there was no default.  This
            problem was introduced in V4.1 and magnified in V4.3.

        12. A couple of info window problems that occur only when there are
            several hundred fields have been corrected.

        13. Beginning with V4.3, whenever a user wanted to modify the primary
            key field with XENTIS/Update, XENTIS requires the user to perform
            a SELECT function followed by a REUPDATE function.  This is due
            to RMS losing its position within the file.  However, a bug was
            introduced that did not allow the user to modify the primary key
            even when using the REUPDATE function.  This problem has been 
            fixed.

        14. A problem occurred in V4.3 that caused fields with print frequency
            "S" to print on the grand total line when data was being
            accumulated.  This has been corrected.

        15. XENTIS allows 150 fields on an output report.  A problem was
            introduced in V4.3 such that if more than 147 fields were output
            on a report, then XENTIS would abort.  This has been corrected.

        16. Under certain very rare circumstances some negative numbers would 
            print as a positive number.  This would occur only if default 
            negative indication processing was used, in other words, a leading 
            minus sign.  This problem has existed for a number of years and is
            corrected in version 4.4.

        17. Using Rdb on Alpha AXP system would sometimes result in an abort
            before a report was produced and sometimes after a report was
            produced.  This was a compiler problem that was resolved.

        18. Specifying a text literal as your output field in XENTIS/File where
            the output file was described by a temporary dictionary would
            result in the text literal always having a length of one byte. This
            problem was introduced in V4.3.
