Yep. I looked it up in a 360 POO. I believe that UNPK just reversed the nibbles in the last byte, but for the rest of it, it has to insert zone nibbles. That would be "F" for EBCDIC, IIRC '5' for ASCII. EDIT and EDMK likewise have to supply zone nibbles. You are correct that all of the values A-F are valid signs. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
