Even with programs called by the menu or get submitted,
I'd prefere to use named activation groups.
Named activation groups are opened at the first call and exist until
either the job ends or an RCLACTGRP (reclaim activation group) is
exectuted. In this way they can be specifically closed, if needed.
But programs running in named activation groups cannot be called
recursively.

If you use activation group *New instead, the overhead of creating
and deleting the activation group will happen each time you call the
program in your job.

For our application, we defined the following rules:
1. programs called by the menu, from command line or with the Cl-Command
   SBMJOB are generated with a named activation group
   (program name = activation group name)

2. programs consist only of a bunch of procedure calls that are
   located in sevice programs.

3. service programs containing insert, update or delete procedures
   are generated with activation group *CALLER.
   This allows us to start commitement control with commitment scope
   *ACTGRP.

4. All other service programs are generated with a named activation
   group. (activation group = service program name)

Hi Jon,

Don't you mean *NEW for the programs called by the menu? Because if you
have the menu as *NEW (which also makes sense), everything else that
gets called with *CALLER is inside the same activation group.
