ClipHelp (C) Version History


     Ver 2.2 - 3 April 1992

     Optional ability to call a UDF on accessing help (a 'pre-help'
     UDF) and/or another on leaving help (a 'post-help UDF') via public
     variables in Summer 87 version and code block parameters in
     Clipper 5 version.  Scope for imagination!

     Fixed bug in both 2.1 vs libraries whereby help screens overlaid
     a junk background when ClipHelp was used in mono mode.

     Facility for users to access full ClipHelp editor features through
     the use of a serial number and code supplied by CISMail, FAX,
     phone or airmail on registration.  Serial numbers and codes will
     also give users access to full features of future versions of
     ClipHelp downloaded from Nanforum or a local BBS.

     Ver 2.1 - 17 February 1992

     Maintenance release.  Corrects an omission in CLHLP501.LIB whereby
     changes to the Application Background attribute made with
     ClipHelp's 'Set Defaults' option were being ignored.

     Ver 2.0 - 3 January 1992

     ClipHelp .OBJ files in earlier versions now replaced with .LIB
     files.

     GrabScreen() added to CLHLPS87.LIB and CLHLP501.LIB.
     Incorporating appropriate calls to this function during
     application development enables whole or specially-defined part
     screen images to be saved to a database called CAPTURES.DBF
     (created and maintained by ClipHelp).  The same function can be
     called in ClipHelp's 'Edit Colors' option to 'cannibalise' parts
     of its help file as it is creating it.

     Images saved in CAPTURES.DBF can be inserted directly into the
     HELP.DAT file complete with color attributes using the new
     'Import' facility of ClipHelp's 'Edit Colors' option, greatly
     reducing the work needed with previous versions of ClipHelp.

     The attribute bytes of all characters not obscured by overlaid
     help data when <F1> is tapped are now changed and restored on
     return to the application.  This avoids unsightly flashing panels
     which could previously arise with Clipper 5's SETBLINK().  The
     default color can be changed using ClipHelp's 'Set Defaults'
     option.

     An optional 'path' command line parameter when running ClipHelp
     tells it where to find HELP.DAT and HELP.TXT files, supporting
     concurrent development of help systems for multiple applications.

     Public variable in Clipper S87 version and additional parameter to
     the solitary function call in Clipper 5 version optionally allows
     HELP.DAT and associated files to be located elsewhere than in an
     application's default sub-directory.

     Ver 1.11 - 12 December 1991

     Checks whether a mouse is in use and if so, saves the condition,
     turns off the mouse while help screens are displayed and restores
     the original mouse condition on exit.


     Ver. 1.1 - 24 October 1991

     Replacement Clipper 5 OBJ module (CLHLP501.OBJ).  All PUBLIC and
     PRIVATE variables removed and replaced with LOCAL or file-wide
     STATIC variables.  Only one line of source code need be added to a
     Clipper 5 application to embrace all ClipHelp facilities.  Context
     sensitivity achieved by calling a function to pass a string/code
     to ClipHelp, avoiding a PUBLIC variable declaration.

     Replacement Clipper 5 C function library (HLPC501.LIB) with
     improved speed over that supplied with version 1.00.
