This is, actually, a request for records - I was using the 1-byte average record size because I thought the original poster wanted to allocate in megabytes. If you want to request records and you know the LRECL or the average LRECL, use AVGREC=U/K/M, and SPACE=(avgLRECL,(pri,sec)) where 'pri' and 'sec' are in records (AVGREC=U), thousands of records (AVGREC=K), or millions of records (AVGREC=M).
My only problem with this was convincing application programmers to use it. I used it all the time, but still found application programmers trying to calculate efficient block sizes (they did, eventually, see the BLKSIZE=0 light) and use various 'space calculators' to come up with a number of cylinders. I proposed, but never got to do, a 'what you don't know about zOS' class to touch on some of these things. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
