Gil and Steve (and probably others who feel the same way), Before you get too whack-happy, there are other reasons why something like this could show up. At some point in the deep, dark past, if the system fell over for whatever reason (power outage, operator - or sysprog - error that caused an immediate drop, etc.) temporary datasets can be left out there. This scenario hasn't happened to me in a long time so I don't know if IBM changed the system IPL to clean up old temporary datasets or not.
If IBM has added a cleanup routine, or if it is found that some poor JCL coder did code a DISP on a temporary dataset, then by all means, whack away. :-) Rex -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Paul Gilmartin Sent: Monday, March 25, 2013 2:01 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Dataset DELETE question : IEBFR14 vs IDCAMS On Mon, 25 Mar 2013 14:38:41 -0400, Steve Thompson wrote: > >Now, go whack the person that wrote the JCL that has the following >similarly coded DD statement: > >//SYSUT3 DD UNIT=3390,SPACE=(CYL,10),DISP=(NEW,CATLG) > >This is what produces a data set name like this: >SYS12048.T104505.RA000.IBMUSER.R0100008 > >The DISP is NOT needed for a "step only" work file / data set.

And for good measure, I'd whack the z/OS (...OS/360?) designer who decided that the proper behavior in this case is to KEEP but not CATLG the data set. I'd have made CATLG without DSNAME a JCL syntax error and never initiated the job. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN The information contained in this e-mail may contain confidential and/or privileged information and is intended for the sole use of the intended recipient.
