Hey Alan!

 AI> In BBBS it looks like that, no colour at all.

Right.  Same with vim and I suspect most if not all text editors.

 AI> Looking at that message in Mystic the word "yellow" is yellow.

Same with 'cat' which can and does work with ansi escape sequences.  For
longer ansified files 'less -r' is probably the better tool, especially
when piped to from 'fold -s -w n' where n = number of columns in the
display.

It is all good.

Life is good,
Maurice

... Don't cry for me I have vi.
