GENSCRNX VERSION UPDATE LOG



                                 1.7a
                                ------


New:  *:CLICK <function>
      Adds invisible button with a WHEN snippet that calls the mouse click
      function specified.  The () after the function name are only required
      if parameters are passed.  In the Windows platform, *:CLICK supports
      text, box, and picture objects while in the MS-DOS platform, *:CLICK
      supports text and box objects. 
      
      Example:
      To have a function called myfnct exectuted from a mouse click on the
      object, place the following in the Comment snippet:
      *:CLICK myfnct
      
New:  GENSCRNX automatically creates two null invisible button at row,col 0,0
      as the first and last GET in the Screen Layout.  Each screen of a screen
      set will have two null invisible buttons with the name corresponding to the
      screen set.  Since the invisible button's WHEN is set to .F., the objects
      are null objects and have no effect on the generated screen.  The purpose
      of this is to allow generic reference to the first or last GET object in
      any screen of a screen set.  For example in a screen set with one screen,
      the first GET would be m.scnobj1 and the last GET would be m.scnend1.
      Example:
      _CUROBJ=OBJNUM('m.scnobj1')

      Example:  The first GET of the first screen of a screen set would have
      an invisible button at 0,0 called m.scnobj1 while the second screen of a
      screen set would have an invisible button called m.scnobj2.

New:  *:SCNOBJ and *:NOSCNOBJ
      *:SCNOBJ specified in the Setup snippet enables the invisible button
      m.scnobjn above to be generated.  Although it is generated by default,
      *:SCNOBJ can be used to override a SCNOBJ=OFF setting in the
      CONFIG.FP/CONFIG.FPW files.
      *:NOSCNOBJ specified in the Setup snippet disables the invisible button
      m.scnobjn above to be generated.  *:NOSCNOBJ can be used to override a
      SCNOBJ=ON setting in the CONFIG.FP/CONFIG.FPW files.
      *:NOSCNOBJ is automatic when either the #NOREAD directive exists in
      the Setup snippet or no GET objects exist for the screen.

Fix:  GENSCRNX properly handles the *:SIZE and *:NOSIZE directives for EDIT
      objects.

Fix:  GENSCRNX enhanced to ensure drivers are executed properly from a project.
      Previously there were rare cases when the 3D.PRG driver was not properly
      adding the 3D effects when building from a project.  GENSCRNX 1.7a contains
      added logic to prevent these conditions from re-occuring.

Fix:  GENSCRNX functions for updating object snippets like instxt1() and instxt2()
      both act identical now.  Both functions will update the Comment snippet only
      while GENSCRNX handles the updates automatically.  The reason both functions
      where left in even thought they are identical is for backward compatibilty.
      Existing drivers should not have to be updated and this is just knowledge
      base information only.

Fix:  *:BASLIB and *:INCLIB are no longer case-sensitive when referencing a library
      name.

New:  The wordsearch() function has been enhanced for improved performance when
      parsing.  The string being searched must be in column one which means it
      cannot be indented with spaces, tabs, etc.

New:  The updpsr() function has been enhanced for improved performance when
      updating an .SPR file.  The larger the .SPR file generated, the more
      increased performance from previous versions.

New:  The 3D effects driver 1.6 for GENSCRNX (3D.PRG) supports a RAISED clause
      for any object.  Previous versions only supported raised lines and boxes.
      The two ways to obtain raised beveled 3D effects are:
      In the Setup snippet:
      *:SCXDRV5 3D
      *:ALL3D RAISED
      or
      In the Comment snippet of a object to have raised 3D beveling:
      *:3D RAISED

New:  The 3D effects driver 1.6 for GENSCRNX (3D.PRG) will require GENSCRNX 1.7a
      or later.  They will both be available simultaneously.

New:  The 3D effects driver 1.6 for GENSCRNX (3D.PRG) supports the REFRESH clause
      for SAY objects when using *:3D for chisled 3D effects.  If the SAY object
      is not set to refresh mode, the 3D box will overwrite the SAY object when
      the screen is executed.

Fix:  GENSCRNX's thermometer properly displays and refreshs text that has
      a length greater than the thermometer window.  This is only a
      cosmetic fix to prevent leftover characters in the thermometer
      window.


---------------------------------------------------------------------------


                                 1.7
                                ------


New:  GENSCRNX now supports multiple drivers per driver hook number to be
      specified in the CONFIG.FP/CONFIG.FPW files.

New:  *:DRVOFF <file>
      Specified in the Setup snippet to disable any driver setting that is
      specified in the CONFIG.FP/CONFIG.FPW.  The number of *:DRVOFF
      directives specified in the Setup snippet is unlimited and the
      files included are retained for all screens in a screen set.  If
      *:DRVOFF is specifed in the Setup snippet in a screen set, then all
      screens following in that screen set will inherit the *:DRVOFF for
      the specified driver.
      Example:
      If the 3D.PRG is specified in the CONFIG.FPW as _SCXDRV5="3D.PRG",
      for the 3D driver to be executed globally for every screen, then
      specifying *:DRVOFF 3D in the Setup snippet would disable the 3D
      driver for that screen.

New:  GENSCRNX creates comments in the Setup snippet as that include the
      the following information at compile time.
      Example:
      *           This program was preprocessed by GENSCRNX.
      *--GENSCRNX 1.7
      *--Screen    C:\SAMPLE\CUST2.SCX
      *--Project   C:\SAMPLE\SAMPLE.PJX
      *--FOXSCX    C:\FOXPRO25\FOXSCX.DBF
      *--Platform  DOS
      *--Time      08/25/93 20:29:46

New:  *:NOWCLAUSES <clause list>
      Removes a list of clauses from the DEFINE WINDOW command of a screen.
      Any list of clauses can be removed (except COLOR) by listing the name
      of each clause separated by a space delimiter.

      Example:
      Add following line in the Setup snippet to remove all FROM, TO, AT,
      SIZE, FONT, and STYLE clauses will be removed from the DEFINE WINDOW
      command:

      *:NOWCLAUSES FROM TO AT SIZE FONT STYLE

      To directly add any of the removed clauses, use GENSCRN's #WCLAUSES
      directive.
      
      Example:
      Add following lines in the Setup snippet to add a custom
      AT <row,col> SIZE <height,width>:

      *:NOWCLAUSES AT SIZE
      #WCLAUSES AT 1,1 SIZE 10,30

      or

      *:NOWCLAUSES AT SIZE
      #WCLAUSES AT {{VPOS}},{{HPOS}} SIZE {{HEIGHT}},{{WIDTH}}

      Note:  The {{<expC>}} evaluates any expression and replace its result
      as source code.  In the above example, the field names are referencing
      the .SCX header record which contains the screen layout window data.

      Example:
      Add following lines in the Setup snippet to add a custom
      FONT <fontface> STYLE <fontstyle>:

      *:NOWCLAUSES FONT STYLE
      #WCLAUSES FONT m.myfontface STYLE m.myfontstyl
      
New:  wordsearch() function in GENSCRNX now supports any memo field snippet
      of the current record instead of only the Comment and Setup snippets.
      wordsearch() is a function used by GENSCRNX drivers to locate
      directives in any snippet of the current .SCX record.

      wordsearch(<expC1>, [[<expL1> | <expC2>], [expL2] ]

      <expC1>
      The character expression that's searched for.

      <expL1> | <expC2>
      The name of the memo field snippet to search of the current record.
      If <expL1> is .F., the COMMENT memo field searched.
      If <expL1> is .T., the SETUPCODE memo field searched.
      If <expC2> is passed instead of <expL1>, the memo field <expC2>
      memo field searched.
     
      <expL2>
      If <expL1> is .F., search uses match words.
      If <expL1> is .T., search does not use match words.

      Example:
      m.str=wordsearch('*:3D')
      The string m.str would contain CHR(0) if '*:3D' was not found in
      the COMMENT snippet of the current record.
      The string m.str would contain the characters following *:3D if
      '*:3D' was found.  If the line contained '*:3D INSET', then
      m.str would contain 'INSET'.

      m.str=wordsearch('#INSERT','VALID')
      The string m.str would contain CHR(0) if '#INSERT' was not found in
      the VALID snippet of the current record.
      The string m.str would contain the characters following #INSERT if
      '#INSERT' was found.  If the line contained '#INSERT BEEP.PRG', then
      m.str would contain 'BEEP.PRG'.

Fix:  GENSCRNX forces SET POINT TO '.' throughout the duration of compiling
      and returns SET POINT TO back to its original after completion.  This
      was added for international support when SET POINT TO is not set to its
      default value during development.

Fix:  GENSCRNX forces SET TRBETWEEN OFF throughout the duration of compiling
      and returns SET TRBETWEEN TO back to its original after completion.

Fix:  GENSCRNX properly executes multiple drivers per driver hook number.

Fix:  GENSCRNX properly surpesses same file from being called more than one
      per driver hook number.

Fix:  GENSCRNX properly pre and post processes all screens in a screen set
      containing more than one screen.

Fix:  GENSCRNX properly executes the platform only check box in the
      Generate dialog setting.

Fix:  GENSCRNX properly disables the *:OUTFILE <file> directive when the
      screen is being generated from a project.  Since FoxPro's Project
      Manager internally stores the expected output file specified in the'
      .PJX file, the generated file must match this file name or the
      project will halt building.

Fix:  GENSCRNX properly reads the CONFIG.FP/FPW files when tab characters
      exist.

---------------------------------------------------------------------------


                                 1.6b
                                ------


New:  *:GENSCRNX <file>
      *:GENSCRNX is used to specify which program is used to generate 
      screen code.  *:GENSCRNX overrides any _GENSCRNX in the
      CONFIG.FP/CONFIG.FPW files.  If both *:GENSCRNX and _GENSCRNX are not
      specified, the default setting is GENSCRN.PRG located in FoxPro's
      start-up directory.  *:GENSCRNX can be used to specify a modified
      GENSCRN needed for a particular screen rather than changing _GENSCRN
      before generating a screen.

New:  *:DELOBJ
      Delete screen object at compile time after pre-processing is complete.
      Use *:DELOBJ for objects that need to reside in the .SCX database
      during pre-processing but not in the .SPR file at run-time.

Fix:  The insertion of a file using #:INSERTTOP <file> when one platform
      of source code is generated is placed after the .SPR file comment
      heading rather than before.  This is not a functionality fix, but
      rather a cosmetic fix.

---------------------------------------------------------------------------


                                 1.6a
                                ------


New:  #:INSERTTOP <file>
      Inserts file at top of .SPR code before DO CASE of cross-platform
      block.  If #:INSERTTOP <file> appears more than once due to
      cross-platform snippets containing the same code, the <file> will
      only be inserted into the .SPR once.  This allows header files
      containing #DEFINE directives to be inserted once per .SPR file
      instead of one per platform inside the DO CASE block.

New:  The AUTORUN function can now be set by either adding AUTORUN=ON in
      the CONFIG.FP/CONFIG.FPW file or setting a public variable
       _AUTORUN='ON'.  Placing *:AUTORUN in the Setup snippet overrides
       AUTORUN=OFF in CONFIG.FP/CONFIG.FPW.  Placing *:NOAUTORUN in the
       Setup snippet overrides AUTORUN=ON in CONFIG.FP/CONFIG.FPW.

New:  The *:EVLTXT directive is automatic and is no longer a GENSCRNX
      directive.  Evaluation of any {{<expC>}} command contained in memo
      fields are automatically evaluated.

New:  *:PJXSET
      Place in the Setup snippet before the *:PRG directive or any *:SET
      directive to force the project information to have priority settings
      when building the screen from a project.
      Example:
      If the following was in the Setup snippet of a screen:
      *:SET MODAL ON
      *:PJXSET
      *:SET READCYCLE OFF
      Then if the screen was generated from the Screen Builder, the READ
      would contain the clauses MODAL and CYCLE no matter what the check
      box settings were set to before selecting <Generate>.  If the screen
      was generated from a project, the READ would contain MODAL no matter
      what the settings were set to in the project but the CYCLE setting
      would be set to whatever the project setting was set to.

New:  When using *:BASOBJ and snippet type is different between library
      and screen surface, the procedure snippet is automatically placed
      into the Cleanup snippet as a unique function and the function
      name is added to the expression.

Fix:  *:IF works properly when used with *:INSSCX or *:INSOBJ directives.

Notes:  If #SECTION 1 is in the Setup snippet, then #:INSERT and #:INSERTTOP
        must be placed after the #SECTION 1 statement.

Notes:  If COMPSPR=ON and DISPSPR=ON and an .ERR file is created forcing
        GENSCRNX to display the .SPR and .ERR files, then the window with
        the .SPR file must be closed before re-generating the .SCX when
        SHARE.EXE is loaded to avoid a sharing violation error.

Notes:  GENSCRNX automatically searches the Setup snippet and Comment
        snippets for any *: or {{ characters to determine of the .SCX
        database needs pre-processing.  Therefore, if any {{<expC>}} need
        to be evaluated and are not in the Setup snippet or Comment
        snippets, they may not be evaluated properly.  If the GENSCRNX
        error mode appears or pre-processing is not being performed when
        it needs to be, simply place *: on any line in the Setup snippet
        to force GENSCRNX to pre-process the .SCX database.

---------------------------------------------------------------------------


                                 1.6
                                ------


New:  *:AUTORUN
      Automatically releases screen after generation and executes generated
      file.  *:AUTORUN is automatically disabled if either a compiled file
      is not properly generated or a compile error was detected via the
      COMPSPR=ON.

New:  *:COMPSPR
      Overrides COMPSPR=OFF in CONFIG.FP/CONFIG.FPW.

New:  *:DISPSPR
      Overrides DISPSPR=OFF in CONFIG.FP/CONFIG.FPW.

New:  *:ENDFNCT
      Place at end of code that follows *:FUNCTION to mark ending of text.
      *:ENDTXT is now used with *:INSTXT and is not used with *:FUNCTION.

New:  {{< <file> }}
      Insert a file at compile time.  The < that follows the open braces is
      the command that evaluates the contents of a file and inserts the file
      at that location.  Note:  The inserted file may contain {{ <expC} }}
      to be evaluated.
      
New:  {{ <expC1> :: [<expC2>] [:: <expC3>] }}
      Insert code from a screen or library object.  <expC1> is the
      library.object name just as in *:DEFOBJ, *:BASOBJ, etc.  Note if the
      library name is not included, the object is searched for specified by
      the *:INCLIB and *:BASLIB directives in the Setup snippet.  Also, if a
      matching object is defined via the *:DEFOBJ directive on the surface
      screen, that object will have proirity over any matching library
      objects.  <expC2> is the string to be evaluated.  After the .SCX
      record is matched, any string can be evaluated (ex. 'VALID' to return
      the VALID snippet).  If <expC2> is null, the COMMENT contents will
      be returned.  <expC3> is the option method name.  If <expC3> is
      included, the text block specified by the matching method defined by
      *:METHOD <name> ... *:ENDMTHD is returned.

New:  *:METHOD
      Place at start of code to mark beginning of method code.

New:  *:ENDMETHOD
      Place at end of the code that follows *:METHOD to mark ending of
      text.

Fix:  Fix for incorrect generation of Setup snippets when screen sets
      contain more than one screen that are pre-processed by GENSCRNX.

Fix:  Proper execution for multiple *:INSOBJ directives.

Notes:  GENSCRNX default behavior does not add * Start of text and * End
        of text messages for the *:INSTXT directive for enhanced
        performance.  To add the commented text (as in version 1.5 and
        earlier) either set OUTTXT=ON in the CONFIG.FP/CONFIG.FPW file or
        set a public variable _OUTTXT='ON'.

Notes:  *:OBJNAM has been renamed to *:DEFOBJ.  For an example, refer
        to the COLOR text object in the sample screen CUST4.SCX.

---------------------------------------------------------------------------


                                 1.5
                                -----


New:  #:SECTION 3
      Used in Setup snippet (like #SECTION 1 | 2) to insert code after GETs
      and before READ in the Screen Layout.  For an example, refer to
      CUST5.SCX.


New:  *:FUNCTION <function name>
      Used in Comment snippet of object to automatically insert a function
      into the Cleanup snippet.  Function needs to be written just like a
      typical FoxPro UDF except that *:FUNCTION is used instead of FUNCTION.
      GENSCRNX will automatically remove the *: from *:FUNCTION.  Only on
      *:FUNCTION can exist per Comment snippet.


New:  *:ENDTXT
      Place at end of the code that follows *:INSTXT or *:FUNCTION to mark
      ending of text to be inserted.


New:  *:SAVESIZE
      Used with *:DEFOBJs to force the SIZE information to be retrieved from
      the library when the object is based in a screen.  For an example, refer
      to the PHONE object in the MAIN library (LIBMAIN1.SCX).


New:  *:SAVEPICT
      Used with *:DEFOBJs to force the PICTURE information to be retrieved from
      the library when the object is based in a screen.  For an example, refer
      to the CONTROL_BAR_ object in the MAIN library (LIBMAIN1.SCX).
      

New:  *:BASBEFORE
      Used with *:DEFOBJs to force any inherited expressions or procedures to be
      inserted before rathre than appended after to any screen surface code.


New:  Referenced library objects can mix expressions and procedures.  The
      expressions are automatically converted to IF/ENDIF blocks.  For example,
      if a VALID object is in the library as an expression and in a screen
      surface is inheriting that object but has a procedure VALID snippet, the
      expression from the library will be converted to an IF/ENDIF block and
      appended to the screen snippet (unless *:BASBEFORE which will force the
      library expression to be inserted before).  If *:BASOBJ is used to
      inherit snippet(s) from a library and the snippet type of the screen
      object snippet is not equal to the snippet type of the library object
      snippet, the snippet that is a function is automatically converted
      into a procedure and appended to obtain the same functionality.


New:  *:PRG
      A Setup snippet directive called *:PRG that is used to automatically
      change the .SPR extension to a .PRG extension and also add the
      #NOREAD PLAIN directive to the Setup snippet.  The *:PRG directive
      used in conjunction with screen objects with the *:INSTXT directive
      will allow a .PRG file to be created that has no GETs, SAYs, or READ,
      while the screen builder Object Order controls the order of the FoxPro
      source code generated in the .PRG file.


New:  Improved error handle routine
        Cancel, Ignore, Suspend options
        Error line can be copied from error window into the clipboard
        Display of current open database, ALIAS, and record number

New:  Improved warning handle routine
        Cancel, Ignore, Suspend options

New:  Warning message defaults to cancel GENSCNRX
        To override, set AUTOHALT=OFF in the CONFIG.FP/CONFIG.FPW

New:  A function in GENSCRNX to allow a public variable or CONFIG.FP/
      CONFIG.FPW setting to globally enable/disable drivers.
      Example:  To disable the 3D driver globally:
        1)  Place 3D=OFF in the CONFIG.FPW file
        2)  Set a public variable _3D='OFF'
        Note:  The public variable overrides the CONFIG.FPW setting


New:  *:OBJNAM <expC>
      For use with the objdata() function for object locating at compile time.


Fix:  *:IF and *:INSTXT works properly for SAY(Refresh) objects.  Code is
      inserted in both Screen Layout and Read Show sections.

Fix:  Building from projects with non-normal ordered records

Fix:  Temporary .SCX, .PJX, and .MEM file names created during GENSCRNX are
      unique instead of fixed for network compatibility.

Fix:  Proper output of Setup snippet for cross-platform screens when the
      snippets are different and PLATONLY=ON in the CONFIG.FP/CONFIG.FPW
      or a public variable _PLATONLY='ON'

Fix:  Fix for *:SIZE directive with EDIT objects and refreshed SAY objects

Fix:  Fix for *:SIZE directive with refreshed SAY objects

Fix:  Fix for *:INSSCX directive when object is smaller than template

Notes:  The *:NOSIZE directive is ignored for EDIT objects

Notes:  For WINMOVE.PRG driver, specify *:SCXDRV2 WINMOVE in Setup snippet

Notes:  For NOSIZE.PRG driver, specify *:SCXDRV3 NOSIZE in Setup snippet

Notes:  For 3D.PRG driver, specify *:SCXDRV5 3D in Setup snippet

Notes:  The following .PRG files previously contained in GSXSAMPL.ZIP
        sample code are now contained inside of GENSCRNX:
        OBJDATA.PRG, OBJSAY.PRG, OBJPOS.PRG, LIBDATA.PRG
        The above files should be deleted if the exist from previous
        GSXSAMPL.ZIP sample code.

                                 1.4a
                                ------


Fix:  _SCXDRVn and _SPRDRVn in CONFIG.FP/CONFIG.FPW for cross-platform screens

Fix:  GENSCRNX should pre-process .SCX if _SCXDRVn is in CONFIG.FP/CONFIG.FPW
      even when no GENSCRNX directives exist in the .SCX

Fix:  Building from projects with header record not RECNO()=1

Fix:  Proper output of Setup snippet for cross-platform screens when the
      snippets are different
