I have now found what I was looking for in the online docs for Watcom C.
Watcom didn't exactly make it easy for those who are new to OS/2
programming to find them, however...

I bought that some time ago, and I agree with your assesment.  It's
certainly a good way to learn PM programming, but at the moment I think
I'll set my sights a little lower and aim for VIO.

I quickly learned that a good deal of the things that I learned about DOS
programming go out the window(s) when dealing with OS/2.  Unlearning habits
isn't easy :(.  For example, accepting that API functions have 'sizes'
(16-bit & 32-bit) isn't easy when you're used to the one-size-fits-all
INT 21 API.

If you can afford it...

Woking?  Where is that in the UK?
