<dt><em>Description</em>:</dt>
<dd><p>Bitwise logical <code>AND</code>.
</p>
<p>This intrinsic routine is provided for backwards compatibility with 
GNU Fortran 77.  For integer arguments, programmers should consider
the use of the <a href="IAND.html#IAND">IAND</a> intrinsic defined by the Fortran standard.

<dt><em>Arguments</em>:</dt>
<dd><table>
<tr><td width="15%"><var>I</var></td><td width="70%">The type shall be either a scalar <code>INTEGER</code>
type or a scalar <code>LOGICAL</code> type.</td></tr>
<tr><td width="15%"><var>J</var></td><td width="70%">The type shall be the same as the type of <var>I</var>.</td></tr>

</dd>
<dt><em>Return value</em>:</dt>
<dd><p>The return type is either a scalar <code>INTEGER</code> or a scalar
<code>LOGICAL</code>.  If the kind type parameters differ, then the
smaller kind type is implicitly converted to larger kind, and the 
return has the larger kind.
