None whatsoever.

Prototypes provide guidance for the compiler - nothing more than that. So the only potential impact is on the length of time to _compile_ because the compiler has to interpret all the protos before it knows which will be used.

What may need to be considered from a perforce perspective is the grouping of the associated procedures into service programs. If you only use one routine in a service program that contains 500 routines then there may be some overhead there for the unused ones. Even so - it is rarely an issue.

I have a service program with many exported functions/procedures and I have a copybook with all the prototypes (no /if defined declarations).
If my program only uses one function from all the prototypes that were included...does having the extra prototyped functions that are never used impact startup performance of my program?
