`IALL`

— Bitwise AND of array elements*Description*:- Reduces with bitwise AND the elements of
`ARRAY`along dimension`DIM`if the corresponding element in`MASK`is`TRUE`

. *Standard*:- Fortran 2008 and later
*Class*:- Transformational function
*Syntax*:-
`RESULT = IALL(ARRAY[, MASK])`

`RESULT = IALL(ARRAY, DIM[, MASK])`

*Arguments*:-
`ARRAY`Shall be an array of type `INTEGER`

`DIM`(Optional) shall be a scalar of type `INTEGER`

with a value in the range from 1 to n, where n equals the rank of`ARRAY`.`MASK`(Optional) shall be of type `LOGICAL`

and either be a scalar or an array of the same shape as`ARRAY`. *Return value*:- The result is of the same type as
`ARRAY`.If

`DIM`is absent, a scalar with the bitwise ALL of all elements in`ARRAY`is returned. Otherwise, an array of rank n-1, where n equals the rank of`ARRAY`, and a shape similar to that of`ARRAY`with dimension`DIM`dropped is returned. *Example*:-
PROGRAM test_iall INTEGER(1) :: a(2) a(1) = b'00100100' a(2) = b'01101010' ! prints 00100000 PRINT '(b8.8)', IALL(a) END PROGRAM
