| <dl> |
| <dt><em>Description</em>:<dd>Write a single character in stream mode to stdout 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>This intrinsic is provided in both subroutine and function forms; however, |
| only one form can be used in any given program unit. |
| |
| <p>Note that the <code>FGET</code> intrinsic is provided for backwards compatibility with |
| <samp><span class="command">g77</span></samp>. 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>. |
