It's NOT for performance; hasn't been for years. It's for extent management! We still are only allowed 16 for non-EF, 123 for VSAM/Liniar/PDSE, etc. We get SB37/SE37 all the time due to these (il)logical limitations. I haven't DEFRAGged for performance for aeons! - 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
