XOR — Bitwise logical exclusive OR
This intrinsic routine is provided for backwards compatibility with
GNU Fortran 77. For integer arguments, programmers should consider
the use of the IEOR intrinsic and for logical arguments the
.NEQV. operator, which are both defined by the Fortran standard.
RESULT = XOR(I, J)
| I | The type shall be either a scalar INTEGER
type or a scalar LOGICAL type.
|
| J | The type shall be the same as the type of I.

INTEGER or a scalar
LOGICAL. If the kind type parameters differ, then the
smaller kind type is implicitly converted to larger kind, and the
return has the larger kind.
