Conversion Routine

The 31 step program uses flag 0 which is initially set at LBL A but not cleared at LBL B. However, at the end of the program flag 1 (!) is cleared. I think this is an error. In any case it's good practice to always initialize a flag and not rely on a certain state at program start, e.g. like this:

Code:

LBL A
SF 0
GTO 0
LBL B
CF 0
LBL 0
...

You say this is a HP67 program, but the keycodes look strange: f and g in the fourth row (that's the one with the ENTER key), flag commands with g prefix and keycodes like 20, 40 or 36. Which calculator does this refer to?
