(paraphrase of the deprecated "me, too!") The same applies to use of temporary data sets, such as the often discussed here limits on those used by TSO TRANSMIT and SUBMIT commands. The limit should be enforced by the job, not by the various applications.

Ideally, the failure should impact the greediest user, not the one who, by happenstance, requests the straw of storage that breaks the camel's back. -- gil -- StorageTek INFORMATION made POWERFUL ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
