<dl>
<dt><em>Description</em>:<dd>Reduces with bitwise AND the elements of <var>ARRAY</var> along dimension <var>DIM</var>
if the corresponding element in <var>MASK</var> is <code>TRUE</code>.
<br><dt><em>Standard</em>:<dd>Fortran 2008 and later
<br><dt><em>Class</em>:<dd>Transformational function
<br><dt><em>Syntax</em>:<dd>
<p><table summary=""><tr align="left"><td valign="top" width="80%"><code>RESULT = IALL(ARRAY[, MASK])</code>
<br></td></tr><tr align="left"><td valign="top" width="80%"><code>RESULT = IALL(ARRAY, DIM[, MASK])</code>
<br></td></tr></table>
<br><dt><em>Arguments</em>:<dd>
<p><table summary=""><tr align="left"><td valign="top" width="15%"><var>ARRAY</var> </td><td valign="top" width="70%">Shall be an array of type <code>INTEGER</code>
<br></td></tr><tr align="left"><td valign="top" width="15%"><var>DIM</var> </td><td valign="top" width="70%">(Optional) shall be a scalar of type
<code>INTEGER</code> with a value in the range from 1 to n, where n
equals the rank of <var>ARRAY</var>.
<br></td></tr><tr align="left"><td valign="top" width="15%"><var>MASK</var> </td><td valign="top" width="70%">(Optional) shall be of type <code>LOGICAL</code>
and either be a scalar or an array of the same shape as <var>ARRAY</var>.
<br></td></tr></table>
<br><dt><em>Return value</em>:<dd>The result is of the same type as <var>ARRAY</var>.
<p>If <var>DIM</var> is absent, a scalar with the bitwise ALL of all elements in
<var>ARRAY</var> is returned. Otherwise, an array of rank n-1, where n equals
the rank of <var>ARRAY</var>, and a shape similar to that of <var>ARRAY</var> with
dimension <var>DIM</var> dropped is returned.
<br><dt><em>Example</em>:<dd>
<pre class="smallexample"> PROGRAM test_iall
INTEGER(1) :: a(2)
a(1) = b'00100100'
a(2) = b'01101010'
! prints 00100000
PRINT '(b8.8)', IALL(a)
END PROGRAM
