Russ, do you have any idea if this affects programs like FDRABR and COPYCAT which create multiple files in the same program execution? The text refers to passed and RETAINed tapes, but it is not clear about multiple OPENs.
We have the default of YES, so I GTF traced a multiple file create on an A/S tape. There is no rewind and read of VOL1 between files. So this apparently only affects tapes that are actually passed to another step.

In any case, it seems that it should be set to NO if all of the systems sharing the A/S tape are OS/390 2.10 or z/OS, in which case they all use the current A/S sharing protocol and the problem of a foreign tape being mounted are nil
