Internally in Rev, all line delimiters are LF, showing Rev's unix
heritage. When Rev writes a text file to disk, it converts the line
delimiter to whatever is the convention for the host OS--ASCII 13 for
Mac, ASCII 13 + 10 for Win, and ASCII 10 for *nix. Conversely, when
it reads text files, it converts line delimiters to ASCII 10.

I think it's because you are looking at the *line*. Since cr is the
line delimiter, it is never included in the text of, say, 'line 3 of
myMultiLineVar'. Instead, look at the whole container:
repeat with myIndex = 1 to the length of myMultiLineVar
