There was also V1, but that was cumbersome. I never used OS/2 for production much.

My interests in Dos are nowadays limited in some FPC work and general interest. I considered this more a thread where things went wrong with Dos.

Back then, if it was good for anything I'd have been happy, yes.

Yes.

Never saw anything special about it. Probably nice for *nixers who had to specify their applications in C source at that time, but for the rest fairly irrelevant.

Like most languages standards, too deliberately terse on the library front IMHO.

The point that is if the wrapper had been 32-bit callable and in the OS, then as time progressed successors and emulators could have hooked it.
