Sorry, but I can't see any Bison related problem here.  It's only C
programming problems.  If you want to change STROUT, then you need a
pointer to it, i.e.

int routine (int id, char *strinp, char **strout)

and use (*strout) where you used strout before.

It doesn't compile.  Please, send something *complete* if you want us
to try it.
