If code has downward-only GOTOs to a single TAG, often you can move all
the code containing the GOTOs and the TAG into a subroutine and then use
LEAVESR instead of the GOTOs.


In our case, the GOTO / TAG is almost always a loop scenario.

Speaking of the venerated GOTO, I found this in the RPG reference:
Use a GOTO operation to specify a branch:
- From a detail calculation line to another detail calculation line
- From a total calculation line to another total calculation line
- From a detail calculation line to a total calculation line
- From a subroutine to a TAG or ENDSR within the same subroutine
- From a subroutine to a detail calculation line or to a total
calculation line.

I stumbled upon that last one in some old code a few weeks ago and was
dumbfounded. I never knew we had that feature (sic) in RPG.
