And if BDW is less than DCBBLKSI-RBC, adjusting the RBC has the effect of quietly discarding the unexpected bytes? If it had been my design, I would have chosen to err on the side of caution, and raised WRONG LENGTH RECORD error in all those cases. -- gil -- StorageTek INFORMATION made POWERFUL ---------------------------------------------------------------------- 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
