Place the `len' length substring of `as' starting at `as[origin]'
in `aresult'.
Return `aresult'.
Note: The copying of as to aresult stops if either the
specified number (len) characters have been copied,
or if the end of as is found.
A negative len generally guarantees that everything gets copied.
