In 1997, I left the Atlanta SHARE meeting early on Thursday morning. Gene Amdahl was waiting for the shuttle bus with me. On the way to the airport, I had the opportunity to ask him some S/360 questions as we were the only 2 people on the bus. One of which was, how did you ever come up with that ED (it) instruction? His reply, "oh, we had fun with that one".

I thought that Gene Amdahl was the principle architect of 360. A search to check my facts seems to reveal that Amdahl, Blaauw and Brooks led the design team. >explain that EDIT is rarely used by COBOL Really? I learned how EDIT works in the early 1970's after seeing it in the code generated by Cobol. As I recall, Cobol used it whenever formatted numeric output was needed. -- Tom Marchant
