| Bill Joy wrote vi in 1976 while at UCB. I know, but it wasn't on the 1BSD tape (ex was I think), the vi command in ex (and the vi command) were on the 2BSD tape (about 78 I think.) Mail was on the 1BSD tape I believe (that is, I thnk I remember...) | I believe MH came later. The Rand distribution, with MH and e, was at a similar time to the 1BSD tape, arund 76-77. Which was first I have no idea, but development on them would have been happening more or less in parallel. | From what I recollect, more people used Mail | than MH and I believe the $EDITOR/$VISUAL convention for | calling an editor was well established. EDITOR and VISUAL are environment variables - therefore did not exist before 7th edition (or 32V) - that is, about 79. All of MH, e, ex, vi, and Mail existed long before those could possibly have been in use. Exactly when EDITOR first appeared I am not sure (it was not one of the env vars used by anthing in the 7th edition - the editor there was just ed - no need to be able to specify an alternative.) VISUAL as an alternative to EDITOR came much later. kre -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers
