REFR means reloadable without changing function or behavior
RENT means multiple users without changing function or behavior,
Classic "bad" code
IF address = 0
Determine and store address
End-if
Branch to address
When refreshed, the address has to be redetermined, but program still works
And, RENT only sets it once when first encountered. But, program works the same
for all callers
I didn't write it, but one of our interface routines to Adabas has done this
for more than 40 years.
