STRING/=
========

Syntax: (string/= <string1> <string2>
          :START1 <number> :END1 <number>
          :START2 <number> :END2 <number>)

This function compares (parts of) strings with
differentiation between upper- and lowercase-
characters. It returns T, when the strings are
not equal, otherwise NIL.

example:       >(string/= "Computer" "Computer")
               NIL
