Clear _all_ does a reasonable job of reseting most macro variable values.
If you use keyword parameters and fill them in dynamically, you can
completely control the values that are being submitted.  Then you could
submit each program to the batch processor via a X command without running
MP Connect.

MP Connect definitely has it's uses and I employ it to speed up processing,
however, it can be difficult to debug.  If a session just hangs there and
you kill it, you will NOT get a log that lets you know where it hung at.
It is also very easy to run into dataset contingencies with MP Connect,
expecially if using permanent format catalogs.
