Re: *entry and PR with same program as EXTPGM

["Bob P. Roche" <BRoche@xxxxxxxxxxxxxxxxx>]

I'm not sure you can say there is an advantage, The program will run 
either way. The only advantage I know, is you don't have to drop out of 
free form to define the *entry parms. I like that they are at the top of 
the program since I used to define my *entry parms in the INZSR subroutine 
that was at the bottom of my programs, but I could have defined it first 
in my 'C' specs, so that's not really an advantage.

Someone replied that you get the prototype checking when called from 
another program using a prototype, But if I understand correctly, The 
calling program verifies your callp to the prototype, nothing compares 
that to the called programs prototype.

There isn't, besides perhaps the ability to use different keywords. I use
the PR/PI method for programs myself, but I usually have this comment:

// *ENTRY

Above it for programmers to search.
