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.
