Tony,

Please consider that SYS?.** datasets might be on volumes that represent the previous running system volumes.

Do the volumes look like previous 'sysres' volumes?

My 2 cents, take some time to investigate the date and contents, might be you don't want to trash them yet.

On the other hand, if you are sure you have the ability to recover your running system and do know what your fall back system is them, blast away.

Just my 2 cents..

ADRDSSU if you have it.

Dump and delete the uncataloged datasets.

Later you can RESTORE with a new HLQ if desired.

//STEP1    EXEC  PGM=ADRDSSU
//SYSPRINT DD    SYSOUT=A
//DASD1    DD    VOL=SER=MYVOL1,UNIT=SYSDA,DISP=OLD
//DASD2    DD    VOL=SER=MYVOL2,UNIT=SYSDA,DISP=OLD
//TAPE     DD    UNIT=3480,VOL=SER=TAPE04,LABEL=(1,SL),
//  DISP=(NEW,CATLG),DSN=USER3.BACKUP
//SYSIN    DD    *
   DUMP DATASET(INCLUDE(**) -
                BY((DSORG NE VSAM) -
                   (CATLG EQ NO))) -

I have inherited a system where nobody bothered to clean-up after
themselves. If I do a DITTO VTOC of all the volumes, I can sometimes
find 5 or 6 copies of the same dataset, some of which are SYSx.*.

I would like to first rename all the uncataloged versions so I can
eventually delete them.

Does anybody know of a free tool that would help with this process?
