Chamara,

In the situation you illustrated, the ExtPgm( ) isn't really required. But obviously doesn't cause any problems. As Adam (I think) said, the PR definitions should be in a copy book somewhere. So in the copy book the ExtPgm( ) keyword makes sense since it may be a candidate for inclusion in another program that calls this one.

I don't know for a fact, but I doubt there is any advantage in using either method to define the parameters (*Entry list). My bet is that it's the PI structure that defines the PList and that the PR is just along (syntactically) for the ride. If that's true (big IF), the compiler will generate the same code for both.

The "advantage" is in the eye of the beholder. Like someone else said, I hated using PList when I moved to free format. When Jon told me about this method at a COMMON session, I jumped on it because, well, it just looks neater.

Hi all,

Abcpgm pr extpgm('ABCPGM')
