HP-48G local variables within subroutine

There is no reason to use compiled local variables here.
If your subroutine was simply
DIVMUL « a b / b DUP * »
and you called it from another program that defined a and b, eg
MAIN « → a b 'DIVMUL' »
then you would need compiled local variables, because when creating DIVMUL, a and b are GLOBAL variables while when calling DIVMUL from MAIN they should be local.
So, create DIVMUL as
DIVMUL « ←a ←b / ←b DUP * »
and MAIN as
MAIN « → ←a ←b 'DIVMUL' »
