Gerson, yes, nicely written! Your program LBL A is exactly the approach used by the "less complex" approach on the 48g.

To Allen what belongs to Allen! The credits are all yours. After posting I realized I had done a small linguistic error. I should have written "Those make for nice HP-42S solutions" as I meant to refer to your original HP-48G solutions, mine being mere ports to the HP-42S.
When you presented the more complex solution, I tried to figure out what your less complex one might be. Then the one I found on the HP 50g was 25-byte long but the check-sum was # BEA0h, so I reached for my HP-48GX and verified the checksum was indeed #D45Bh on it. Multiplying by .5 instead of dividing by 2 gave a different checksum than #7FE7h, which means I've found only one of your other solutions. I'd like to know what are the other 7-command 27.5-byte solutions. The pdf gives the initials of the authors and timings only.

Regards,

Gerson.

P.S.: Here's an 11-byte 5-step HP-42S solution:

Code:


00 { 11-Byte Prgm }
01>LBL C
02 CLΣ
03 Σ+
04 RCL 14
05 RCL- 12
06 RCL× 15
07 .END.
