| <dt><em>Description</em>:</dt> |
| <dd><p>Determines the minimum value of the elements in an array value, or, if |
| the <var>DIM</var> argument is supplied, determines the minimum value along |
| each row of the array in the <var>DIM</var> direction. If <var>MASK</var> is |
| present, only the elements for which <var>MASK</var> is <code>.TRUE.</code> are |
| considered. If the array has zero size, or all of the elements of |
| <var>MASK</var> are <code>.FALSE.</code>, then the result is <code>HUGE(ARRAY)</code> if |
| <var>ARRAY</var> is numeric, or a string of <code>CHAR(255)</code> characters if |
| <var>ARRAY</var> is of character type. |

| <dt><em>Arguments</em>:</dt> |
| <dd><table> |
| <tr><td width="15%"><var>ARRAY</var></td><td width="70%">Shall be an array of type <code>INTEGER</code> or |
| <code>REAL</code>.</td></tr> |
| <tr><td width="15%"><var>DIM</var></td><td width="70%">(Optional) Shall be a scalar of type |
| <code>INTEGER</code>, with a value between one and the rank of <var>ARRAY</var>, |
| inclusive. It may not be an optional dummy argument.</td></tr> |
| <tr><td width="15%"><var>MASK</var></td><td width="70%">Shall be an array of type <code>LOGICAL</code>, |
| and conformable with <var>ARRAY</var>.</td></tr> |

| |
| </dd> |
| <dt><em>Return value</em>:</dt> |
| <dd><p>If <var>DIM</var> is absent, or if <var>ARRAY</var> has a rank of one, the result |
| is a scalar. If <var>DIM</var> is present, the result is an array with a |
| rank one less than the rank of <var>ARRAY</var>, and a size corresponding to |
| the size of <var>ARRAY</var> with the <var>DIM</var> dimension removed. In all |
| cases, the result is of the same type and kind as <var>ARRAY</var>. |
