Description. Scatters elements of `MASK` to positions of the
result indicated by index arrays `INDX1`, ..., `INDXn`. An
element of the result is true if and only if the number of true values
among the corresponding element of `BASE` and the elements
of `MASK` scattered to that position is
odd.

Class. Transformational function.

Arguments.

MASK must be of type logical. It must not be scalar.

BASE must be of type logical with the same kind type parameter as
`MASK`. It must not be scalar.

INDX1,...,INDXn must be of type integer and conformable with
`MASK`. The number of `INDX` arguments must be
equal to the rank of `BASE`.

Result Type, Type Parameter, and Shape. Same as `BASE`.

Result Value. The element of the result corresponding to the
element of `BASE` has the value `PARITY( (//) )`, where () are the elements of
`MASK` associated with as described in
Section .
