RE: RPG ILE and *INLR

["Andrew Borts" <Andrewb@xxxxxxxxxxxxxxxxxxx>]

OK - here's the thing;
        All the sub-programs/binding/stuff makes
1) Bigger Code (more memory)
2) Bound Code
3) Slightly easier to understand - since we're making our own
functions...
4) Slower Code (from second hand tests.... So nobody yell @ me...)

The memory saving dynamically linked "CALL"  W/O *INLR takes 200ms (old
number?) to load into memory ONCE- then it's there until it shut's down.

Polite programmers have written "when I send you a '1' here - you shut
down all nice like" that Joe is talking about, but honestly - when the
people signed off, the same thing happened anyway..

Does anyone have current benchmarks about this?

I apologize.
