3390 full track size is ca. 56K, and 3380 is ca. 47K. But you were right - 32K is still not optimal for 3390.

IIRC it would be 1 block per track (track size being 48K) Half track blocking or 24K is probably the best, IMO. My memory is drawing a blank for 3380 (but 36K maybe right) so 18K. Best to use blksize=0 unless the damn program over rides the blocksize, if so call the vendor.

If not, then do so. -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@bama.ua.edu] On Behalf Of Staller, Allan Sent: Tuesday, August 16, 2011 8:10 AM To: IBM-MAIN@bama.ua.edu Subject: Re: ABEND - 637-04 This is consistent with reaching to volume count limit of 255 volume/dataset (on tape). On DASD, the limit id 59 volumes Check the JCL manual or "Using Datasets" for more detail. You have 2 options: 1) Move the file to higher density media. E.g. 3490 ---> 3590 2) logically split the file into 2 (or more) pieces so that each piece requires less than 255 volumes HTH, <snip> I am receiving a message IEC026I during the volumes copies, at the point of 255 volumes. Does the volume limits to be copied is 255 ??? What ABEND should be returned when 255 copies volumes is reached ??? </snip> ---------------------------------------------------------------------- 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 NOTICE: This electronic mail message and any files transmitted with it are intended exclusively for the individual or entity to which it is addressed.
