When an arithmetic operation or

is performed, the answer is placed in the

X-register, the number formerly in the X-register is copied into the LAST X register,

and the stack drops. When the stack drops, the number in the Z-register is copied

into the Y-register, and the number in the T-register is copied into the Z-register but

also remains in the T-register.

The diagram on the next page illustrates the stack operation when 8 ÷ 2 is

calculated. (Assume that the stack and LAST X registers have already been loaded

with the numbers shown as the result of previous calculations.)

Percentage Functions

When any of the three percentage functions is performed, the answer is placed in

the X-register, the number formerly in the X-register is copied into the LAST X

not changed when a percentage function is performed.
