use-revolution Digest, Vol 16, Issue 81

[Mark Smith]

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 
would be:

put char -3 to -1 of it into myExtension

negative numbers in this context simply mean counting backwards from 
the end of the string.

Cheers
