GSB 30
GSB 40
RTN

i.e. only support GSB to a few specific line numbers. Then you could have one or two small subroutines, which can occasionally make sense with a 49-step program memory.

What about a simple GSB 49 instruction. A GTO nn placed there would enable a subroutine just about anywhere in memory.
