The integer in the second word of the stack is divided by the in-
teger on the TOS. The two words are then deleted. The second
word is replaced by the quotient, and the top word is replaced by
the remainder.

The top two words of the stack are multiplied in integer form.The
two words are deleted and the least significant word of the doub-
le length product is pushed onto the stack. If the high order 17
bi ts of the double length pr od uct (includ ing the sign b it of the
second word) are not all zeros or all ones, Overflow is set.
