Maybe you know about using procedure pointers and assigning them to a variable that is used on a CALLP, if I remember Jon's presentation right from the RPG@DB2 summit - he has an example of the world's most expensive pocket calculator - an iSeries. But this lets you have a single call statement but using different procedures based on the arithmetic operation you are processing at the time.

The point is the programer has to explictly decide which function to call
ahead of time given certain
input

Kinda, but in reality you could have two of the samed named externally
defined service program sub procedures, and whatever one is found first is
the one that will be used. So you still have some dynamic-ness outside of
programming. In this case it would be based on *LIBL which could be
considered the same thing in the end I guess.

Cool, but I think your stretching to call this override or inheritence.


How about "Manual Override"? :-)
