As of version @value{VERSION}, @code{$1} cannot be processed with
usual string functions, because it is not null-terminated. This
limitation will be removed in future versions.

+It is possible, however, to pass it to an external program, using
+@code{write} with three arguments (@pxref{I/O functions, write}), e.g.:

+@smallexample
