| <dt><em>Description</em>:</dt> |
| <dd><p><code>FDATE(DATE)</code> returns the current date (using the same format as |
| <code>CTIME</code>) in <var>DATE</var>. It is equivalent to <code>CALL CTIME(DATE, |
| TIME())</code>. |
| </p> |
| <p>This intrinsic is provided in both subroutine and function forms; however, |
| only one form can be used in any given program unit. |
