   Your type mismatch error is occuring because you are trying to
assign a STRING result (from copy) to a CHARACTER variable. You
can reference portions of a string directly as characters by
using Txt [x]. Your ordinal type expected error was from ORD
trying to get the ORDinal of a STRING result again.
