If it makes reasonable sense to me to use a return variable, then I'll use
a return variable. This allows me to:
- use it in a expression
- make an SQL UDF out of that expression, if needed.

I see a lot of stuff (even here) still created as separate program calls.
Where there are multiple parameters and only one of them is expected to be
returned. I say make it a subprocedure with a return variable. Then, if
you have the dinosaur that will only use a subprocedure at gunpoint then
simply wrap the subprocedure with the separate called program and they can
use that. It shouldn't be the other way around.
