9.130 IANY — Bitwise OR of array elements

Description:
Reduces with bitwise OR (inclusive or) 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 = IANY(ARRAY[, MASK])
RESULT = IANY(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 OR 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_iany
  INTEGER(1) :: a(2)

  a(1) = b'00100100'
  a(2) = b'01101010'

  ! prints 01101110
  PRINT '(b8.8)', IANY(a)
END PROGRAM
