I have a routine with one optional argument that I am unable to use “PP to Routine…” with. The routine doesn’t show up in the list of available routines. Is there any way around this?

You can’t set PP directly to a routine with optional argument, because then haven’t you defined the argument.

You need to set the PP to the instruction that calls the routine with an optional argument.
