My recollection was that the slashed letter O was a COBOL thing. I'd just gotten out of the Navy where I'd learned to slash the number 0, and it was a wrench.
I just looked at one of my 1401 Autocoder books, and it doesn't show the slashed O (or 0). Neither does the 7040 MAP book or listing. 73, doug From: "Ron D'Eau Claire" <[EMAIL PROTECTED]> Date: Fri, 15 Feb 2008 20:29:03 -0800 In the late 1960's some IBM system programmers decided to use the solidus (slash) through the letter "O" to differentiate it from the simple circle that was used for zero at Sylvania's Electronic Defense Laboratories where I worked as a writer. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
