Are you sure about UNPACK, EDIT and EDMK? My recollection is that
- UNPACK does not care about content. It just re-arranges the nibbles. - EDIT and EDMK do not ever create packed data, do they? And I think they honored both D and B as negative indicators for input.

I doubt that it's still functional. Did COBOL ever exploit it? Bit 12. As Charles noted, it was only used for the setting of the sign and/or zone nibble in decimal numbers in pack decimal arithmetic, as well as UNPACK, CVD, EDIT and EDMK. When set to 1, it indicated ASCII mode. I don't know what you mean about Cobol exploiting it. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
