SS - Save stack (saves the entire stack, including L)

Then there are a few different restore routines that restore the stack in various ways, called just before the program returns

What about Dave's idea of placing the specs at the end, RPN style ?

We could even combine LBL + SS as say, LBLS, saving 1 step.
This make the code steps same as before stack saving feature was added.

LBLS "TEST"
...
RTN 12 ; 1 input, 2 output

This seems to give more flexibility to the code too.
Example, for bad input, error out, and restore the whole stack ... RTN 00
