I get a new empty string each call previously?
It's one of the differences Rebol has with other languages. When you assign
a string to a word, like this:
s: ""
You're literally assigning 's to the string just after the 's in the
above line. Therefore that string, just after the "s:" is where the contents
of the string refered to by 's reside.
By using the 'copy, as in:
s: copy ""
you get a fresh copy of the next thing after the 'copy word, into 's.\
The colon ":" is the set-word operator, which is literally:
set the word to the left to point to the right.
Which is not quite assignment in conventional languages.
I hope that helps!
