OK, I got curious and looked it up. ASCII signs were A and B. http://bitsavers.trailing-edge.com/pdf/ibm/360/princOps/A22-6821-0_360PrincOps.pdf
Too wonderful for words!168 pages for the whole book, including a description of how the front panel worked. The first sentence mentions that it is a "solid state" system. It's an image scan and not searchable so I can't readily confirm my recollections of "ASCII mode" but I do think what I said is correct.

Going just from memory here -- too lazy or too inconsequential to look it up. 1. Yes, the bit has gone away. 2. It never did much. After all, CLC or MVC does not care if the data is ASCII, EBCDIC or Klingon. All it ever did was control the sign nibble in packed results: C and D for EBCDIC, some other sign configurations for ASCII. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
