In the case of CLOSE TYPE=T (TCLOSE) I believe you should see multiple type 64 records with only one type 62 (VSAM Open) SMF record, and that type 62 will be (naturally) created before any of the type 64s. If that's true you would discard any but the last type 64 records' data. (Someone might want to verify that first though.) You wouldn't want to be doing a large number of TCLOSEs per run... on the order of 1's or maybe 10's but not 100's and certainly not 1000's. You'll be swatting a gnat with a nuclear device in short order with this approach. (These statistics just aren't that important.) -- Tom Schmidt Madison, WI ---------------------------------------------------------------------- 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
