You are right, offset() works only with characters (string)

Offset does not appear to be working correctly anyway.

well, you can see these lines being equivalent:
put "abcdefgabcccablmnopoq" into theChars
delete char 1 to 3 of theChars
put offset("c",theChars)
and you'll get 7, which is right.
and doing the same for your next example, gives
you 3 which is right too.
