HP-25 Emulators suggestion

Apologies, I was trying to refer to the program tokens used for the comparison functions

55

Code:


49 x GTO                -   GTOnn
49 x if X<=Y then GTO   -   [f][GTO]nn
49 x if X=Y  then GTO   -   [g][GTO]nn

The 33 was better in that comparisons used 1 token each, then they can use any of the GTO codes as a branch if TRUE.

33

Code:


49 x GTO                -   GTOnn

f X<=Y
f X>Y
f X!=Y
f X=Y
g X<=0
g X>0
g X!=0
g X=0

So, there is a big token saving, 147 vs 57 (plus there are 6 extra comparisons) The [f] and [g] keys also used one extra in the 55 and not in the merged keycode 33.
