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 corresponding element of
`BASE` and all elements of `MASK` scattered to that position are true.

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
`ALL( (//) )`, where () are the
elements of `MASK` associated with as described in Section .

. `ALL_SCATTER( (/T, T, T, F/), (/T, T, T/), (/1, 1, 2, 2/) )`
is `,T, F, T,, plus 1filll
-1;T, F, T,; plus 1filll
-1:T, F, T,: plus 1filll
-1.T, F, T,. plus 1filll
-1T, F, T, plus 1filll-1.`
