In many ways, I agree with that sentiment. However, it does saddle us with obsolete ways of doing things. Reference the entire thread on PDSes and their problems. And DASD allocation. I would prefer if SMS storage pools could act a bit more like a UNIX filesystem - allow a dataset to grow as needed without limit other than the size of the storage pool. No more maximun number of extents per volume and 59 volumes. No more specifying SPACE in JCL at all - make it obsolete and ignore it. Granted the super large DASD volumes of today reduce some of this. That is, for those of you (not us) who can adopt them. We have (own) an old 2105 and won't upgrade (no money, literally). Speaking of which, any jobs in DFW area of TX? -- John McKown Maranatha! <>< ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
