[TUHS] Old screen editors

At the Stanford Information Systems Lab while I was there 1976-81, we had a series of PDP-11s. The first one I remember was an 11/34 running V6 and later V7. It was later upgraded to, I think a /45 and finally a /70. At first everyone used ed, then Prof. John Gill hacked it to add a command, I think ‘%’ that was the equivalent of .-10,.+10p which on our 9600 baud Hazeltine’s was a glimpse of the future. At some point we got ex/vi, but before that we got the “Rand Editor” re, which was a perfectly functional screen editor, if you squinted a bit. Does anyone here know the place of re in the history? Later, Gill went off for a sabbatical at Yorktown Heights and came back to complain about having to use SOS on the mainframe. He reported, however, that global search and replace was very fast. -L Also a few years later I got Dave Conroy’s version of microemacs. I complained about the key bindings and he told me to use the “change configuration” command, or cc.
