Always a good idea to allow the job to terminate cleanly.

Typically no need to place the services in common (may be different running on
real old ESA hardware).

Look at the 0C4 information - it will tell you a bit.

Look at the PSW and at what is being referenced.

As a side point, your statement above indicates a bug.

The service A/S must be swapped in when the service is invoked. The code
itself need not (unless it is invoked by some service running in a state that
cannot tolerate page faults).

Have you considered how to update them on a running system? Or that a failure
in one can affect all of them?

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
