I was able to find a VSAM dsn (Prod) that I would like to mimic. This is what the LISTCAT says: KEYLEN ---77 AVGLRECL---77 BUFSPACE ---13824 CISIZE--- 4608 MAXLRECL--- 4096 Would this be correct if I apply your suggestion: KEYS (77 0) - SHAREOPTIONS (2 3) - CISZ (4608) - BUFSPACE (13824) - RECORDSIZE(0 4601)) - The reason why I am not using the LIKE parm is because we are trying to diagnose a problem. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
