ISTR this was because the answer wasn't specified in the POO when the machines that implementd the feature were being developed, and so the POO was changed to make it model-dependent because two systems were implemented differently and couldn't be changed to be consistent. Am I correct, or is there a parity check in that block? ---------------------------------------------------------------------- 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
