I think that what was meant by "character I/O" was essentially that the
editor could talk ANSI, VT100 or similar escape sequences to a terminal
over an RS-232 line, rather than doing BIOS calls or video memory manipul-
ation like the Turbo Editor toolbox probably does. I haven't seen the
Turbo Editor Toolbox code, but I would imagine that it would not be an
impossible task to isolate those sections that actually perform screen I/O
and convert them to use whatever escape sequences are needed.

The only other Pascal editor I have come across is the one in the
Software Tools in Pascal book by Kernighan and Plauger. It isn't a screen
based editor, and bears more than a passing resemblance to "ed" I am
told. I have heard of a project that used this editor as a basis for a
fully fledged screen editor, but I can't put my finger on where I saw it now.

Hope this is of use,
