- You are right and they are wrong. There are _some_ parts that are 16Bit. Though
- the only one I know of was the old (GA Version) graphics engine. Since the
- service pack it is 32Bit. OS/2 has the old APIs for 16 apps and perhaps the
- texmode I/O functions are 16Bit code. But as I understand IBM wants to move
- to PM-only operation, so it would be logical not to change that to 32Bit code.
-
- If it was a 16Bit OS, how could such things like the 32Bit GNU compilers exist
- without an OS/2-extender like the DOS-extender version ?
