<dl>
<dt><em>Description</em>:<dd>Bitwise logical <code>OR</code>.
<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="IOR.html#IOR">IOR</a> intrinsic defined by the Fortran standard.
<br><dt><em>Standard</em>:<dd>GNU extension
<br><dt><em>Class</em>:<dd>Function
<br><dt><em>Syntax</em>:<dd><code>RESULT = OR(I, J)</code>
<br><dt><em>Arguments</em>:<dd>
<p><table summary=""><tr align="left"><td valign="top" width="15%"><var>I</var> </td><td valign="top" width="70%">The type shall be either a scalar <code>INTEGER</code>
type or a scalar <code>LOGICAL</code> type.
<br></td></tr><tr align="left"><td valign="top" width="15%"><var>J</var> </td><td valign="top" width="70%">The type shall be the same as the type of <var>J</var>.
<br></td></tr></table>
<br><dt><em>Return value</em>:<dd>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.
<br><dt><em>Example</em>:<dd>
<pre class="smallexample"> PROGRAM test_or
LOGICAL :: T = .TRUE., F = .FALSE.
INTEGER :: a, b
DATA a / Z'F' /, b / Z'3' /
WRITE (*,*) OR(T, T), OR(T, F), OR(F, T), OR(F, F)
WRITE (*,*) OR(a, b)
END PROGRAM
