service program signatures

[brian <bsl04@xxxxxxxx>]

I'm confused about service program signatures. It seems as though IBM is
telling me that if I add an export to my service program, the signature
of the service program will change, and I'll have to recompile all the
programs that use the service program, which seems pretty unreasonable.

I'd rather have things so that it isn't necessary to recompile a program
that uses the service program unless there is an API change, not just
because I add a new export or something.

Thanks for advice.
