This is not the same thing, Joe. The Turbo C psuedo-variables are referenced
as the register values at that point in the code. When you call int86, 
you are setting up a routine which loads the register variables from
REGS and SREGS, calling your favorite interrupt and then reloading the
variables back from the registers. This is, however, different than the
psuedo-variables. In Turbo C, if you had a line of C which read:

	int x = _AX;

The resulting 80x86 code would be 

	mov [x],AX		(x in this context is dependant on memory 
				 model)

This cannot be done in MSC 5.1. It can't.

Cheers!
Steve
