Anthony,
as long as it is still possible to have a variable named "e", this is fine
by me.

This really belongs on the xTalk list. FYI, MetaCard maps ASCII 10 to all
of the following constants: lineFeed, return and cr.
So, given that is how Scott intended these constants to be, I'd use
"linefeed" for ASCII 10 and re-map return and cr to ASCII 13 on Mac, to 10
on Unix and to 10 and 13 in a row on Windows.

Sounds fine. But again, also put that on the xTalk list to discover any
pitfalls.

I think we can do that because the first word on a line is always a
command (or control structure) in xTalk.

That's sensible.

Just 4 billion? Aww... c'mon! <g>
I think all of us can live with that limit (it's on a per-handler basis,
right?)
