SYNTAX

o result = iany(array[, mask])
o result = iany(array, dim[, mask])

DESCRIPTION

Reduces with bitwise or (inclusive or) the elements of ARRAY along dimension DIM if the corresponding element in MASK is TRUE.

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

Sample program:

   program demo_iany
     integer(1) :: a(2)

a(1) = b’00100100’ a(2) = b’01101010’

! prints 01101110 print ’(b8.8)’, iany(a) end program demo_iany

STANDARD

[[Fortran 2008]] and later

CLASS
