Re: [TUHS] pre-more pager?

The first and second BSD has cr3 "This filter simulates chuck haleys cr3, stopping output after each page (22 lines) to wait for a carriage return, sending 22 more lines, or a EOF, sending 10 more lines." In the Berkeley terminal rooms, the dumb terminals beeped incessantly so most of the bell speakers had been disconnected. Their \emph{cr3} pager tool rang the terminal bell and waited for a carriage return after every 24 lines. The terminals also rang the bell when the cursor advanced near the right margin on output or keyboard input (like a typewriter bell).\cite{halbert-jchac1-4} % TODO: mention cr3 stty mode? % archives/1970s/2bsd/src/cr3.c says 22 lines and no mention of sound % what about that? So Dan Halbert\index{Halbert, Dan}. who arrived in 1978 as a first-year graduate student, wrote a pager called \emph{more} that printed ``--More--'' instead of ringing the bell and accepted the space instead of carriage return to continue. Plus it could take multiple filenames and print a line of colons around the filenames. This was inspired by his use of the ITS timesharing systems as an undergraduate at MIT that put a ``--MORE--'' prompt at the bottom of the screen when displaying files.\cite{halbert-jchac1-4} His friends and fellow graduate students, Geoff Peck\index{Peck, Geoff} and Eric Shienbrood\index{Shienbrood, Eric}, greatly expanded it, adding various options -- and \emph{more} was added into the next distribution.\cite{halbert1} Date: 17 Jun 2010 @MISC{halbert1, author = {Dan Halbert}, howpublished = "Personal correspondence", year = 2010, month = jun } @ARTICLE{halbert-jchac1-4, author = "Dan Halbert", title = "{THE "MORE" COMMAND IN UNIX}", journal = "Journal of the Computer History Association of California", year = 1994, month = "April-June", volume = "1", number = "4" }
