    This program copies a NUL-terminated string from one location to
    another.  The main feature of this program is the use of a separate
    assembly language module, "copy.s", for the actual copy-string
    function: it is an example of mixing C and assembly-language programs.
    Please make sure that you read the source code to "copy.s"!
