<dl compact="compact">
<dt><em>Description</em>:</dt>
<dd><p>Returns the upper bounds of an array, or a single upper bound
along the <var>DIM</var> dimension.
</p></dd>
<dt><em>Standard</em>:</dt>
<dd><p>Fortran 95 and later, with <var>KIND</var> argument Fortran 2003 and later
</p>
</dd>
<dt><em>Class</em>:</dt>
<dd><p>Inquiry function
</p>
</dd>
<dt><em>Syntax</em>:</dt>
<dd><p><code>RESULT = UBOUND(ARRAY [, DIM [, KIND]])</code>
</p>
</dd>
<dt><em>Arguments</em>:</dt>
<dd><table>
<tr><td width="15%"><var>ARRAY</var></td><td width="70%">Shall be an array, of any type.</td></tr>
<tr><td width="15%"><var>DIM</var></td><td width="70%">(Optional) Shall be a scalar <code>INTEGER</code>.</td></tr>
<tr><td width="15%"><var>KIND</var></td><td width="70%">(Optional) An <code>INTEGER</code> initialization
expression indicating the kind parameter of the result.</td></tr>
</table>

</dd>
<dt><em>Return value</em>:</dt>
<dd><p>The return value is of type <code>INTEGER</code> and of kind <var>KIND</var>. If
<var>KIND</var> is absent, the return value is of default integer kind.
If <var>DIM</var> is absent, the result is an array of the upper bounds of
<var>ARRAY</var>.  If <var>DIM</var> is present, the result is a scalar
corresponding to the upper bound of the array along that dimension.  If
<var>ARRAY</var> is an expression rather than a whole array or array
structure component, or if it has a zero extent along the relevant
dimension, the upper bound is taken to be the number of elements along
the relevant dimension.
