Hi Booth,
The PI is equivalent of the *Entry parm declarations. The PI must only be used in the program being CALLED.
The PR is used by CALLERS who need to execute your program. The /Copy member will contain the Prototype, and any "data type" (D-specs) definitions that need to be known to the caller in order to successfully call the program.

Subject: Re: EXTPGM() in PR/PI
I figured out my problem, once folks made it clear I was on the right
track. It works. But I haven't yet figured it out.
As soon as I commented the PI statements in the /copy source statement
then everything worked So, when does one use the PI? To what purpose?

If you use a variable name then that variable must be defined in the program.
