4-level stack manipulation on 12c

[Don Shepherd]

I guess I should document the reason that I wanted to get 5, 17, 5, and 17 on the stack in the first place. I wanted a little MOD function for my 12c and I realized if I arranged these numbers in the stack in that order, a simple \(\div\) INT \(\times\) - would give me the standard formula for MOD: 17-(int(17/5)x5). So the final 12c program is (after entering 17 in Y and 5 in X):

ENTER
ENTER
-
RDown
X<->Y
LastX
\(\div\)
INT
\(\times\)
-


Many thanks Werner.
