If I understand your question correctly, all HP-UX Fortran
implementations preconnect logical unit 5 to stdin, unit 6 to stdout,
and unit 7 to stderr.  Thus

	write(7,*)"hello world"

will go to stderr.  This preconnection can be overridden with an
explicit OPEN statement to the unit in question.

It's also possible to use shell input/output redirection (i.e.  <, >)
and piping facilities to redirect stdin, stdout and stderr to the
locations of your choice.
