The most elegant solution is to use rmh.library:
/*
** Notify test
*/
file = 't:test'
call addlib('rmh.library', 0, -30, 0)
/* Start filenotification */
id = rmh_startnotify(file)
/* Error starting notify */
if id < 0 then exit 10
/* Signal to wait for */
signal = rmh_notifysignal(id)
/* And wait...*/
rmh_wait(signal)
/* When script reaches here file has appeared or changed */
exit

Rolf
