CXL Revision History
------------------------
Version 4.1 - September 4, 1988
1. Support for Mix Power C has been added.
2. Complete BIOS video support has been added. This also will replace
the CGA snow reduction in previous versions.
New:
_vbios - global variable, 0 = direct video, 1 = use BIOS.
putchat() - write character/attribute at cursor position.
Modified:
box_(), fill_(), printc(), and prints()
- now support both direct and BIOS screen writes.
Deleted:
_cgasnow - global variable, no longer supported.
boxd() - now supported by box_().
filld() - now supported by fill_().
printcd() - now supported by printc().
printsd() - now supported by prints().
waitvret()- no longer supported.
3. The window hide and unhide functions are now high level (use
handles, not pointers). This makes the hiding and unhiding of
windows much easier. The prototypes for whide() and wunhide() have
been modified. A new global variable, _whrec, was added for hidden
window management.
4. The internal mouse support has been enhanced. Mouse movement is
smoother and there are no longer mouse "boundaries". Mouse button
presses can no longer be queued.
5. A new global variable, _dvcheck, has been added. This allows for
DESQview checking to be turned off during videoinit().
6. A new format character type, '%', has been added for cvaltype(),
inputsf(), winpdef(), and winputsf() functions. This type allows
numbers, '0' thru '9', and space.
7. The setkbloop() function was not working properly on systems without
a mouse because of a bug in getxch(). Fixed.
8. In the sysdate() function, date codes 3 & 4 were returning the same
result. Fixed. Thanks to Michael Hackman in Washington.
9. In the systime() function, for the time codes 2 & 3, the AM/PM
indicator was not being changed from AM to PM until 1:00 PM. Fixed.
Thanks to John Metzker in Oregon.
10. Menuing and data entry functions weren't being properly supported on
single line borderless windows. Fixed. Thanks to Mark Hall in
Michigan.
