Use Turbo C to write code for OS/2? Sure! The following restrictions
should be noted:

1) Many of the Turbo C library routines will NOT work (and some of them
will even cause unresolved external errors at link time). In general
you should use the OS/2 API calls rather than the Turbo C library
routines.

2) The program I wrote all this for did not have any need for the
environment and command line arguments, so I did not convert these
routines. I plan to do so at some point in the future, but I *do*
have MSC 5.1 now, so the urgency is somewhat lessened.

3) The replacement startup code has a hard-coded stack size (2.5k). If
you wish to change stack sizes, you will need to reassemble this module.
Dynamic stack size setting is *not* currently operational.

4) No support is provided for the 80x87 or for Turbo C 2.0+'s graphics
capabilities.

5) Only the LARGE memory model is supported (though it is easy enough
to modify C0.ASM to change this).

6) You *must* use the OS/2 linker; TLINK will *not* work. See the
enclosed .CMD file for an example of a correct link.


A sample comm program is also provided. This specialized comm program
is designed to talk to a host via a direct-connect 19.2k asynch link.
Although it is not terribly useful in the generalized world of Pc
communications, it *does* serve to illustrate the art of perverting TC
to operate under OS/2. Good Luck!

For questions, support, other OS/2 (or DOS) programs, and lots of
fine discussions (among other things), please call:
