-- PAvatar Revision Log --

1.50   --  Bugs fixed: Possible incorrect ANSI clear screen, ANSI reverse
 7-Apr-93  color was odd, highlight window would lock up the terminal, the
           TTY routine would scroll an extra line at the bottom of the screen
           if the cursor wraped around.  Many more minor bugs were also fixed.

           IMPORTANT:  This release breaks the units up into three units to
           allow overlays.  You MUST call the InitUnit routine of the main
           PAvt150 unit before doing anything else.  See the manual for
           details on what major changes have been made since 1.17.

           NEW: VT-52 Support, "ANSI" music support, AdLib/SoundBlaster FM
           sound support, 30-40% speed increase.  TP/BP 7.0 units are now
           included.  TTYCharh hook allows access to data after control codes
           have been processed.  The small PAvt0 unit has been discontinued.
           The DV_Pause procedure has been renamed to IdlePause; it now
           gives up time to all multitaskers.  More sound support routines
           have been added to allow better control.  The main PAvt150 unit
           can be overlayed.  The SetTerminal procedure has been added to
           replace the old ANSI_Only and Level0_Simulation routines which are
           no longer supported.  Please read the manual carefully!

1.17   --  Bugs fixed: The ANSI request cursor position was not responding
23-Dec-91  correctly.  Replacement SwapVectors procedure has been dropped,
           use Set_Sound_backg (read the docs).  There were mis-calculations
           in the unit's fill and highlight area routines which resulted in
           an improper display when not using window number 0.
           Two new procedures have been added.  The In_Command function
           allows you to determine when the interpreter is in the middle of
           processing an Avt/ANSI command.  The UpdateCursor procedure can
           now change the cursor position easily.  The demo program now
           checks the validity of coordinates passed to it's hooks.

1.15   --  Bugs fixed: When a sound in made under DESQview with the PAvt1
 6-Oct-91  unit, it would overwrite a random memory location.  When issuing
           a set cursor style command the same thing could happen.  This
           has been fixed.
           There is now an easy way to control the sound that the unit will
           make via a new procedure "Set_Sound_backg", and a new variable
           "Sound_Stat".  All of the Avatar/1 queries are now supported.
           Previously only the ID query would respond.  (see the
           QUERIES.DOC file for details.)  The demo programs have been
           combined into one with an include file for the hooks in the event
           that you want to use the code in your programs.  The demo
           program's screen writing has been sped up 30%.

1.10   --  Added a procedure to set the active screen size without having
 7-Sep-91  to reset it with the ResetTerminal procedure.  There is now
           a slimmed down version (PAvt0) included which supports level 0+
           and ANSI-BBS only.  The unit names have changed to better
           reflect the name of the package.

1.01p  --  Fixed a bug in the DESQview_Version function which caused it
25-Aug-91  not to work properly.  Added an enhanced SwapVectors procedure
           to allow dos shells and swapping exec commands.  Before the
           interrupt $1C hook wasn't being restored and usually resulted
           in a lockup.  (Thanks to Mark Cook for noticing that bug.)
