Re: Calling Program with a Procedure Interface

Hello Buck,

No.  PR is defining a PROTOTYPE.  Both procedures and programs can be
prototyped.  The prototype is simply a definition of the call interface.

PI defines a procedure.  An ILE program comprises one or more procedures so
using PI to replace *ENTRY PLIST is simply defining the main procedure of
the program.  The compiler will automatically create a program entry point
procedure (PEP) thus any ILE program will contain at least two procedures
(even in OPM emulation mode i.e., DFTACTGRP(*YES))

Confusion arises because of differences in behaviour when using
DFTACTGRP(*YES) and DFTACTGRP(*NO).  CRTBNDRPG and DFTACTGRP(*YES) requires
that prototypes refer to program objects.  DFTACTGRP(*NO) allows prototypes
to refer to either programs or procedures using the EXTPGM and EXTPROC
keywords.

Given that you are writing an ILE/Activation Groups for Beginners series I
thought you should be particular in your own use of the terminology.

Simon Coulter.
