No, we have users sorting data with path names as input. Just ran a test. Single path input, concatenated, all work fine, unless they add a DD DUMMY between them. As a side note, DFSORT doesn’t do a good job with dynamic sortwk allocations with PATH input because it cannot accurately determine the input filesize. I had opened a ticket with IBM on this, and all I got was "this is the way it is". My only option was to tell my developers to hardcode sorkwk datasets in their job.

That would be imprisoning your users in the twentieth century. Prohibiting "DD *" is also unduly harsh. A similar question applies to Shmuel's suggestion of DEVTYPE. The definitive test should be for DSNAME='NULLFILE'. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN This e-mail transmission contains information that is confidential and may be privileged.
