| <dl> |
| <dt><em>Description</em>:<dd><code>ANY(MASK [, DIM])</code> determines if any of the values in the logical array |
| <var>MASK</var> along dimension <var>DIM</var> are <code>.TRUE.</code>. |
| |
| <br><dt><em>Standard</em>:<dd>Fortran 95 and later |
| |
| <br><dt><em>Class</em>:<dd>Transformational function |
| |
| <br><dt><em>Syntax</em>:<dd><code>RESULT = ANY(MASK [, DIM])</code> |
| |
| <br><dt><em>Arguments</em>:<dd> |
| <p><table summary=""><tr align="left"><td valign="top" width="15%"><var>MASK</var> </td><td valign="top" width="70%">The type of the argument shall be <code>LOGICAL</code> and |
| it shall not be scalar. |
| <br></td></tr><tr align="left"><td valign="top" width="15%"><var>DIM</var> </td><td valign="top" width="70%">(Optional) <var>DIM</var> shall be a scalar integer |
| with a value that lies between one and the rank of <var>MASK</var>. |
| <br></td></tr></table> |
| |
| <br><dt><em>Return value</em>:<dd><code>ANY(MASK)</code> returns a scalar value of type <code>LOGICAL</code> where |
| the kind type parameter is the same as the kind type parameter of |
| <var>MASK</var>. If <var>DIM</var> is present, then <code>ANY(MASK, DIM)</code> returns |
| an array with the rank of <var>MASK</var> minus 1. The shape is determined from |
| the shape of <var>MASK</var> where the <var>DIM</var> dimension is elided. |
| |
| <dl> |
| <dt>(A)<dd><code>ANY(MASK)</code> is true if any element of <var>MASK</var> is true; |
| otherwise, it is false. It also is false if <var>MASK</var> has zero size. |
| <br><dt>(B)<dd>If the rank of <var>MASK</var> is one, then <code>ANY(MASK,DIM)</code> is equivalent |
| to <code>ANY(MASK)</code>. If the rank is greater than one, then <code>ANY(MASK,DIM)</code> |
| is determined by applying <code>ANY</code> to the array sections. |
| </dl> |
| |
| <br><dt><em>Example</em>:<dd> |
| <pre class="smallexample"> program test_any |
| logical l |
| l = any((/.true., .true., .true./)) |
| print *, l |
| call section |
| contains |
