The two length expressions evaluate to numbers - so you're actually
saying (using your example of 12345678):
put char 5 to 8 of it into myExtension
However, transcript can count backwards as well as forwards, so simpler
put char -3 to -1 of it into myExtension
negative numbers in this context simply mean counting backwards from
the end of the string.
