Since you already posted that you have no data class active and a null SMS configuration, it is unlikely that DFSMS has any effect on block size. If the data was written with QSAM, then QSAM performed the blocking (per the DCB parameters specified on the DD statement used to identify the output dataset) as well as constructing the RDWs and BDW. You also posted that the problem was with the BDW and not the RDWs. What do you think the problem is? How did you determine that? Can you post the first 8 bytes of the block in question (BDW+RDW, no proprietary data)? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
