ROY WATSON had something deep to write about C/C++

The answer is yes and no.  If you stick with ANSI standard C stuff
(text only, no graphics) your programs will be almost identical for
DOS, OS/2, Unix, and so on.  Some of my DOS programs compiled for OS/2
with zero changes, but others required significant ones.  If you use
graphics, routines that call BIOS functions, or DOS weird memory mode
far????() functions, you will have to make changes in your programs. 
To get the best use out of OS/2, you will have to learn and use even
more stuff (that won't work in DOS).  In other words, learning the main
features of C is a good thing to do, no matter what OS you use.  Then
you can go on to bigger and better things.

Right now, my machine has a C and a C/C++ compiler for DOS and one
C/C++ for OS/2, with a second OS/2 C/C++ compiler sitting on the shelf.
