Ted, Here is the original email. Nothing about DASD that I can see, although he does mention "space" which could imply DASD:
"All, currently I'm playing around a little bit with the SVC99 DYNALLOC. When I try to allocate a rather large Dataset, I (sometimes) need to specify DALVLCNT (Dataset volume count). Now... I wonder it it would be safe (or "ok") to specify 255 in all cases, even when allocating a small dataset. The documentation says "DALVLCNT specifies the maximum number of volumes an output data set may require."... **MAY**... So... If I don't care if the dataset is a multi-volume or not (I just want to be sure the dataset can be allocated somehow if space is somewhere available), is it safe/ok to specify 255 and let z/OS decide to allocate multi-volume or not? Thanks, Michael" Tom Harper IMS Utilities Development Team Neon Enterprise Software, Inc.

I believe it's built by DFSMS code, which could be argued to be part of z/OS. But ownership of the code is a diversion here. >59 volumes is a DASD restriction, not an allocation restriction. You can dynamically allocate a 255 volume tape data set. I thought the OP was discussing DASD, but I could be wrong. - Too busy driving to stop for gas! ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- 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
