o result = iall(array[, mask]) o result = iall(array, dim[, mask])
Reduces with bitwise AND the elements of ARRAY along dimension DIM if the corresponding element in MASK is TRUE.
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.
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.
Sample program:
program demo_iall integer(1) :: a(2)a(1) = b00100100 a(2) = b01101010
! prints 00100000 print (b8.8), iall(a) end program demo_iall
