In a sense, i need none of the 3 options..
What i need is a library that allows me to (as i said) control/alter
the screen resolution, have pop-up/disappearing text boxes for user I/O
(as i said), and write graphics to the screen on an X/Y pixel basis (may
have indicated that).
Now (as i mentioned before) i have had and used Watcom Fortran since
version 10, and now have 11.0C from OpenWatcom.
There are complete screen routines, but only for DOS.
Does this help?
BTW, Microsoft is a liar, and contradict themselves, concerning
memory.
In one place, they say that Win98/98SE cannot support more than
512Mbyte. FALSE; the limit is 1Gbyte.
In another place they say that "all" windows GUIs will support 4Gbytes
(for the user). FALSE.
In yet another place they say that the windows GUIs will only allow
access to 2Gbytes (TRUE).
The info concerning PAE indicates ZERO support, has mucho cautionary
indicators, and sez that it is slow as all heck.
Now the /3GB switch is something new...will try it in Win2K.
BTW, while it is not possible to use more than 1Gbyte of RAM in
Win98SE, i strongly recommend that you do not install more than that!!
The video will default to 16 color low-res mode (same as the "safe"
mode), and the system will bitch until you set the mode to the
"default".
