| <dt><em>Standard</em>:</dt> |

| <dt><em>Syntax</em>:</dt> |
| <dd><p><code>RESULT = SHAPE(SOURCE [, KIND])</code> |
| </p> |
| </dd> |
| <dt><em>Arguments</em>:</dt> |
| <dd><table> |
| <tr><td width="15%"><var>SOURCE</var></td><td width="70%">Shall be an array or scalar of any type. |
| If <var>SOURCE</var> is a pointer it must be associated and allocatable |
| arrays must be allocated.</td></tr> |

| expression indicating the kind parameter of the result.</td></tr> |
| </table> |

| </dd> |
| <dt><em>Return value</em>:</dt> |
| <dd><p>An <code>INTEGER</code> array of rank one with as many elements as <var>SOURCE</var> |
| has dimensions. The elements of the resulting array correspond to the extend |
| of <var>SOURCE</var> along the respective dimensions. If <var>SOURCE</var> is a scalar, |
| the result is the rank one array of size zero. If <var>KIND</var> is absent, the |
| return value has the default integer kind otherwise the specified kind. |
