RE: EXTPGM keyword

David,

You have to distinguish between two different ways of using a prototype
with EXTPGM:
1) As a prototype for calling other programs. The EXTPGM name determines
the program that gets called;
2) As a way to define your own *ENTRY PLIST (in combination with a
procedure interface) - here the EXTPGM name does not really matter. You
will get an RNF3776 message with severity 10 in your compiler listing.

What Rob was trying to point out to you is that you will get into trouble
if you start using this prototype in other programs. But before you do
that you should at least change the internal name ('prc') to something
more useful. Using the program name for internal as well as external name
seems obvious here.

Thanks all.

So the name XXX210 would be the program called if I did a CALLP
using the prototype in my module XXX110 compiled into program
XXX110. As the call is from a CLP this never happens. The name
XXX210 is never actually used.

It's just an accident waiting to happen!?
