|
<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>

|
<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.
