Hi Charles,
I believe the form,
A and B
is for bitwise and logical operations whereas the form
and [A B]
exits on the first false value it encounters in its block of conditions.
So REBOL is spoiling you too :^)
Your example then would look like (you don't need your parens either):
if AND [
2 = length? p: parse filename "."
not none? find pick p 2 "htm"
][...]
Regards,
Brett.
