Sorry, I must be missing something, why "appropriately Dax"?  What's Dax?

Thanks for that.  If my understanding is correct, OS/2 uses 512Mb selectors
to maintain combatibilty with 16-bit code.  If support for 16-bit code were
removed (hey, what about 32-bit device drivers ), I believe they
can change to 4Gb (or is it 2Gb, with the upper 2Gb reserved for OS/2
itself - it's a while since I read up on this) selectors without breaking
existing apps.

bcnu,

Richard.
