Subprocedure in a module

[The TrekTeam <trekteam@xxxxxxxxxxx>]

Hi All,

I'm attempting to learn subprocedures and don't quite get something.
I've got subprocedures in a single program all figured out, but when it
comes to a subprocedure in a seperate (nomain)module that's used in the
entry module, I'm lost.
Does anybody have a small example that they would like to share?

-or-

Do I need to code the Prototype in the main (entry) module and also in the
bound (nomain) module?
Do I need to use the EXTPROC keyword on this Prototype?
Do I have to call the subprocedure with a CallP? or can I use it like a BIF?

Hope these questions make sense...

Thanks,
Capt.j
