+<dt><em>Description</em>:</dt>
+<dd><p>Read a single character in stream mode by bypassing normal formatted output. 
+Stream I/O should not be mixed with normal record-oriented (formatted or 
+unformatted) I/O on the same unit; the results are unpredictable.
+</p>
+<p>This intrinsic is provided in both subroutine and function forms; however,
+only one form can be used in any given program unit.
+</p>
+<p>Note that the <code>FGET</code> intrinsic is provided for backwards compatibility
+with <code>g77</code>.  GNU Fortran provides the Fortran 2003 Stream facility.
+Programmers should consider the use of new stream IO feature in new code 
+for future portability. See also <a href="Fortran-2003-status.html#Fortran-2003-status">Fortran 2003 status</a>.
