IAND — Bitwise logical andAND.
     RESULT = IAND(I, J)
     | I | The type shall be INTEGER. 
 | 
| J | The type shall be INTEGER, of the same
kind as I.  (As a GNU extension, different kinds are also
permitted.)
      | 
INTEGER, of the same kind as the
arguments.  (If the argument kinds differ, it is of the same kind as
the larger argument.)
