For a RECFM=V data set, BLKSIZE must indeed be 4 greater than LRECL. That is to allow room for the Block Data Word. The Record Data Word is included in LRECL. For a RECFM-VB data set, the BLKSIZE must be at least 4 bytes greater than LRECL. For RECFM=VS or VBS, the BLKSIZE can be smaller than these limits. The maximum BLKSIZE for DASD is 32760. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
