Eric Shienbrood at Berkeley wrote "more"
around 1979, and it was the
standard BSD pager. It was inspired by the --More-- option in the ITS
terminal driver at MIT.
Daniel Halbert wrote to comp.society.folklore in 1994:
"I was a first-year graduate student at UC Berkeley in 1978. I had
been an undergraduate at MIT, and had used the ITS timesharing systems
there, which ran on PDP-10's. ITS put a "--MORE--" at the bottom of
the screen when one typed out files [..]
So I wrote a simple "cr3"-like program, but had it print "--More--"
instead of ringing the bell. I had it accept space instead of carriage
return to continue, because that was what I was used to from ITS."
Wikipedia says "more" was written by Daniel Halbert and expanded by Eric
Shienbrood and Geoff Peck.
