	Definately, but it sure beats having to AllocMem() the block.

	It would be nice if one could have a salloc() call ... allocate memory
	off the stack.  Although Aztec (and lattice?) use a frame pointer, they
	apparaently also push and pop the registers using the stack pointer,
	so the call would have to be implemented like:

		ptr = salloc(bytes)	(allocates on a longword boundry)
		spop()			pops the allocated stack frame, must
					call before return statement / end of
					subroutine.
