When porting the program to the HP-75C I noticed an error in line 720.

720 FOR J=N-1+2 TO -1 STEP -1

The first 1 should be an I:

720 FOR J=N-I+2 TO -1 STEP -1

Please correct it if you haven’t done so yet. This should make the program a little less slow.
I am away from home and have brought only the HP-75C along. Also, I can’t make your links work. Sorry for the mistake!
