Here is factorial from V2N10P11 of PPC Journal:

01 STO 0
02 GTO 05
03 -
04 ST0 x 0
05 1
06 X<Y
07 GTO 03
08 X=Y
09 RCL 00
10 GTO 00 (or R/S)

That's a nice one.

Except that

1) I cannot find X<Y anywhere on my HP-33C;

2) The stack is not properly handled.

What calculator was that program written for?

Gerson.
