Each job certainly gets a new copy Gary - it may even get more if the SRVPGM is *CALLER.

David said that the SRVPGM is the one calling the *NEW PGM and I read it as saying that it was running in QILE and assumed it was specified to do so.

Now that you raise the question I realize that the esteemed Mr. Gibbs did not provide sufficient information to answer the question definitively.

The number of copies of the SRVPGM will depend upon its AG attribute. If it is specified as QILE - then as long as there is an active invocation of the SRVPGM then it will be used. There would however be a new copy created if the SRVPGM had an AG attribute of *CALLER.

I am very interested in this topic because I don't have a good
understanding of service programs and activation groups.

Jon's answer surprises me because I have thought each system i job
receives a "new" copy of a service program, and that activation groups
are "a job within a job", and therefore expected the >new< activation
group of the external RPG program would get a "new"
copy of the service program.

Thanks for the opportunity!

My questions are:

When the service program calls the external RPG program, should the activation group change from QILE to a new activation group?

Yes - it will change to *New

When the external program calls back into the service program, will a new copy of the service program be loaded ... or will it call back into the original service program that invoked the external program?

Original copy should be used.
