need help with FCAT program for HP 42S

[Thomas Klemm]

If you wonder why LBL 14 is used and not LBL 99 to indicate a NO-OP: it is the highest one-byte label.
From LBL 15 on they consume two bytes.

And then they give the precious byte away with a useless use of a RTN statement:

Code:

89 RTN
90 END
