[ColorForth] About ";;"

["Mark W. Humphries" <mwh@xxxxxxxxxxxxxxx>]

I've used the same concept in my (non-color) forth for years, in fact it's
my only backward branching structure.
I use the name ;AGAIN

Cheers,
 Mark W. Humphries

I changed the subject - sorry, i'm always sluggish, just
producing posts by replying to a different thread and forgetting
to change the subject. Dumb me.

So it's not a Chuck Moore invention after all?
Ok. So, what do you think of my (mis)interpretation of
";;" as a compiler word that always jumps back to
the last defined word entry?

Maybe i invented something useful just by misunderstanding
other peoples ideas. ;-) I tend to leave it like that -
of course, OCF is not really Color Forth, so i don't urge
the Color Forth people to pick that up. At least, i like
it a lot. I'm using tail recursion all over the place.
