Nelson, if you do add *CL to your prototypes, make sure you recompile
all the things that use the RPG prototype - any RPG caller compiled
without the *CL would stop working.  Alternatively, if you do have a
case where you need to have a CL caller, you could create a *CL wrapper
for your procedure.

Regarding how CL relates to prototypes, it doesn't really, but you can
still get some of the benefits of prototypes even if all the callers or
even the procedure itself isn't compiled using the prototype.
