I would think maybe it could be if you're using QSAM and doing PUT MOVE, but if you're doing PUT LOCATE, it would have to return the address of a buffer for you to put the next record in. BSAM would likely be more complicated. -- Tom Marchant ---------------------------------------------------------------------- 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
