Paragraph 2 of Subclause 9.5.4 of 16-007 states

       Every input/output statement except an OPEN, CLOSE,
       INQUIRE, or WAIT statement shall refer to a unit
       that is connected to a file and thereby make use of
       or affect that file.

If external unit 10 is preconnected (9.5.5), the program
shown is standard conforming.
