I can tell one thing to NOT do. I tried something similar for one particular job that involved lots of modules, and got into trouble because I saved a pointer to the values in another module, instead of having it return the values each time I needed them. That worked just fine in test, but failed intermittently in production because apparently the variables in modules that are not in the invocation stack can get moved around by the operating system, and external references to them don't get updated.

Typically, I have a separately bound program I call that keeps the job
level values, and I bind in a module to keep static variables at the
program level.  So, I have a program that returns J_SESSION, and both
Program A and Program B call it through an EXTPGM call.  However, each
has its own P_CALLLEVEL value, which it gets through an EXTPROC call to
a bound module.

In the world of service programs, can I emulate this?
