Yes, there is plenty room for improvement. But since this is an old program of yours ("a while back") I assume your skills will have improved by now. So how would you code this today?

It should work on most HPs with a RAN# function. If you insert your own random number generator this should even include most programmable calculators. Maybe after renaming the labels A and B and/or use line addressing, and replacing X=Y? with X=0? after X and Y have been subtracted. The X<0? may take some care on calculators that do not have such a test, but it can be done.

Regarding the program: may I ask two questions?

The program is supposed to generate a number between 1 and 4. But in fact the number can be between 0 and 4. ?!?

The program first calculates a random integer between 0 and 9. Then it checks if it is ≤ 4. If not, it is discarded and a new number is calculated. But... why doesn't the program simply directly calculate a number between 0 or 1 and 4 ?

Sorry if I didn't understand something here, but I just want to ask.
