Does PC ASM have a MOVEM command? On the M68k MOVEM shoved the contents of
any or all (of 16) 32-bit registers to an area of memory. One technique was
to clear as many registers as possible, and dump the contents to the screen.
If you could clear as many as 15 registers, then that would be a whole 60
bytes cleared in the same number of cycles as it would take about 5 move.l
instructions (32-bit move).

Is this not possible on the PC? It seems like a very basic command to me.
