[comp.lang.c++] Zortech C++ v2.1 on OS/2

1. How does the OS/2 implementation of ZTC++ compare to the MS-DOS one?
2. How much trouble is it to port programs in ZTC++ from MS-DOS to OS/2?

If your program is a "vanilla" program (like a compiler!), all that is
necessary is to relink the .OBJ files with the OS/2 runtime library instead
of the DOS runtime library. Of course, if you call BIOS functions directly,
access hardware directly, etc., there will be additional work involved.

Note that it is very difficult to port code that uses the mouse to text
mode OS/2. The MOU functions under OS/2 are totally different and
significantly less capable than the INT 33 mouse api under DOS.
