RE: RPG procedures

[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

If you need to use the programs with dynamic calls you have two choices:

1.)  Leave the plist in the called program and prototype it in the calling
program using the "extpgm" keyword on the D spec with the program name.
This will give you a prototyped dynamic call.  You can do this with programs
where you have may have a good reason not to convert from RPG Classic.

2.) Convert the called program to RPGIV.  Put a prototype and procedure
interface in the called program to replace the plist.  Use crtbndrpg to
compile. Prototype it in the calling program as in choice 1.  Again you'll
have a prototyped dynamic call, but you'll have the features of ILE
available to you.  The converted program can still be called from RPG
Classic programs.  (Activation group *CALLER on the compile is good for
this.)

I'm not a purist; I think there are situations where option 1 is a
reasonable choice.  There are also a lot of situations where a dynamic call
is, for all practical purposes, as efficient as a bound call.
