Prototypes are only used at compile time to check the parameter definitions,
i.e. number of parameters, data types of the parameters and all additional
options.
Prototypes are not used at runtime.
But the complete service program gets activated, even if only a single
procedure is called.
Because it is only a single service program, only a single object has to be
found and loaded into memory.
Even if you have thousands of prototypes embedded in your service program, I
assume there will be (almost) no performance difference.
BTW we have a lot of service programs with 10th or even 100th of procedures,
but I never found that activating those service programs (even if multiples
are used) will take considerably time.

Subject: Performance impact of unused prototyped functions/procedures
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?
Thanks!
