Huh?  Where did you get that idea from what I wrote?

A module that exports a procedure needs both PR (prototype) and
PI (interface) specs.  Normally, the PI is specified in the
source file as part of the procedure and the PR is specified in
a /COPY member included using a /COPY spec in the modules source.
The compiler does not hunt around looking for things - the
programmer needs to explicitly specify these things.

On the other hand, a module that uses a particular procedure
needs just the PR specs.  It gets them by including the /COPY
member that contains them.
