Bit Operations on Floating-point Data
-------------------------------------

   `g77' does not allow `REAL' and other non-integral types for
arguments to intrinsics like `And', `Or', and `Shift'.

   For example, this program is rejected by `g77', because the
intrinsic `Iand' does not accept `REAL' arguments:

     DATA A/7.54/, B/9.112/
     PRINT *, IAND(A, B)
     END
