Since this simulator is limited to 99 steps, I loaded all the constants into registers, even financial registers, and replaced many of the arithmetic operators with RCL arithmetic to save steps.

May I draw your attention to this 95-step program for the 29C? I think it can be ported to other calculators. However, the 38C is a bit tricky since a modulo subroutine is called and the 38C offers no GSB. The program can even be shortened as the linked version calculates all easter dates in the entered year and the following ones. If you don't need this simply omit steps 83...86.

Bob, if you use [​code] and [​/code] tags around your listing it will be properly formatted:

Code:

01 - 21 0        STO 0
02 - 22 71 5     RCL ÷ 5
03 - 24 61       INTGR
04 - 21 1        STO 1
05 - 21 4        STO 4
06 - 31          ENTER
07 - 86 71 0     RCL ÷ .0
08 - 24 61       INTGR
09 - 21 41 4     STO - 4
