HP 15C Combination Curiosity (bug?)

[Eddie W. Shore]

Very interesting to know, Gene. I'm glad that the overflow error is not being caused. I will remember to run labels using the GTO, label, R/S from now on. This method helped solve (for lack of a better word) the flashing problem with Problem 3 on both the Limited Edition and Collector's Edition.

What happens if I try the GTO, label, R/S method with the PSE instruction?

Code:

Code:

LBL E

The 15C Collector's Edition works correctly (the PSE is fixed!).


Not so much with the Limited Edition:
f [ E ]/GSB E: 3 (?) displays, it blanks, it shows 30
GTO E R/S: 3 flashes (the 10 is ignored until it again), and then 30 flashes
In neither case 1 is shown.

Thank you Gene for looking into this!
