varargs

It is a truism that MS-DOS prefers that arguments be passed register-wise; in
part this is due to the anticipation that the routine in question to receive

the arguments is an interrupt-routine with interrupts (hopefully) disabled,
so it must proceed about its business most hastily, less a (possibly) more
desrving interrupt get neglected.
   Some architectures -- most notably, the IBM-360/370 -- allowed for "load
multiple" and "store multiple" commands which saved the whole bank of regis-
ters in one instruction.
