# To subscribers of the xforms list from "T.C. Zhao" <tc_zhao@yahoo.com> :
Just tried it on linux using DEMOS/inputall
(pasted a few k lines of junk and things seem to work
ok).
I'll look at it on SGI soon.
BTW, input field is not really meant to be an editor
as the internal data structure is completely inappropriate
for large amount of text (the internal buffer is
a single buffer with no concept of "lines" at that level).
As the buffer grows large, editing becomes very inefficient.
Of course the structure also dictates that anything
that needs to be done on a per-line bases (color a line
differently, e.g.) is expensive (and a hack). That
said, hack never stopped me from implementing some
good features.
