Is there anyone out there who has experience assembling 32-bit OS/2 v2.0
programs using Microsoft's MASM 6.00b.  I thought that I could use the 
flat memory model but LINK386 chokes on the object code.  LINK386 does not
complain if I use the normal segmented model but the EXE created generates
a 000E trap. 

Any pointers would be greatly appreciated.
