Jeff
agreed in that it depends what operating system level u r at.
The latest releases don't 'obey' the level any where near as much as
they used to.

Removing the QINTER jobq from QINTER subsystem  is a good idea
but as previously suggested, you apear to allow the users to do too much.

They would onl find another jobq to use instead - even QCTL !
