Sysline on a vt100

[Leif Samuelsson]

Well, life isn't always as simple a one would think. It turned out
that I hadn't tested my TERMCAP with VI properly. VI has 24 lines
hard-coded in at least one place which defeats the new definition.

A work-around is to fool VI to think that we don't have region scroll,
without fooling any other programs (like scame). We can do this by
turning off the set/restore cursor capabilities. Unfortunately, VI no
longer does any scrolling, but puts '@' on removed lines instead.

It's easy to fix VI for those who have source. Just replace '23' with
'LINES-1' in file ex_vadj.c, function vdelline(). Then remove the
':sc@:rc@:' below.

Here is the revised TERMCAP line for my script:

    setenv TERMCAP `echo "$TERMCAP" | sed -e 's/:/:li#23:i2=\\E[1;23r\\E[23;1H:is=\\E[1;23r\\E[23;1H:sc@:rc@:cl=50\\E[24;1H\\E[1J\\E[1;23r:hs:es:ts=\\E7\\E[24;%dH\\E[1K:fs=\\E8:/' -e 's/=2\\E/=\\E/g'`

And here is the full TERMCAP entry for those who prefer:
