If you were waiting and you saw in a dump that the first byte of the ECB was zero, that means that someone zeroed the byte when they shouldn't have. If you have an ECB with the wait and post bits off and an RB address in it, the wait bit must have been zeroed after the WAIT was issued and POST must not have been issued. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
