Hi Louis,
Your function didn't do what you expected because BREAK does not return a
value by default. You
could use the /return refinement on BREAK though to return a TRUE.
So you change
if find x y [true break]
to
if find x y [break/return true]
An alternative is to use the RETURN keyword instead of break.
So you can use this instead:
if find x y [return true]
These two will work. In the case where the function does not find anything
it returns none - which is probably what
you want. For me I would probably add a "RETURN none" as the last line in
the function to explicitly make this happen
but this is a personal preference.
HTH!
Brett.
