- <dt><em>Description</em>:</dt>
- <dd><p>Read a single character in stream mode from stdin 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>.
