What did I miss, how does this have anything to do with more? I thought more did real simple types of screen control, and wouldn't even have to use te/ti things. If I'm wrong, I'll assume I lost the thread here, and keep quiet. > Michael Smith <msmith@atrad.adelaide.edu.au> wrote: > > > > scott@block:~> echo $MORE > > > MORE: Undefined variable. > > > > alias more ? > Let's see here... > > scott@block:~> alias|grep more > mroe more > scott@block:~> which more > /usr/bin/more > scott@block:~> file /usr/bin/more > /usr/bin/more: FreeBSD/i386 demand paged dynamically linked executable > scott@block:~> ldd /usr/bin/more > /usr/bin/more: > -ltermcap.2 => /usr/lib/libtermcap.so.2.1 (0x8022000) > -lc.2 => /usr/lib/libc.so.2.2 (0x8026000) > scott@block:~> echo $TERMCAP > /homes/scott/term/termcap > > Aha!
