- Just as a followup here to this thread; OS/2 is indeed a 32-bit OS.
- Certain parts of it *were* 16-bit, i.e. GRE, etc. and some parts of the
- HPFS still are. This is bound to change though to 32-bit. I think.
- Corrections are always welcome, though.
-
- OS/2 is NOT a 16-bit os, emulating a 32-bit one, at all! But it does
- deal with programs that run in 16-bit mode. OS/2 comes with *thunks*,
- which convert any 16-bit requests to 32-bit ones and vice versa, for
- programs that need this kind of support. Just beginning to imagine the
- gymnastics required to achieve that is - yes you've guessed it - one
- hell of a story.

- Nick.
