I think this is one of those personal preference things. I'm just a lazy
typist, so I hate having to put "CallP InitModule" in every calling program.
If the SrvPgm takes care of it's own initialization, then it's more of a
"black-box" and I don't have to think about it anymore.

At the present time, it's just me, myself, & I. Obviously, this gives me a
tremendous amount of freedom. I'm able to pick and choose the technologies
that I use without interference - as long as I continue to deliver a
solution on time & budget.

I sympathize with those of you who don't have the same opportunity.
