Reduces with bitwise OR (inclusive or) the elements of ARRAY along dimension DIM if the corresponding element in MASK is TRUE
.
Fortran 2008 and later
Transformational function
RESULT = IANY(ARRAY[, MASK]) 
RESULT = IANY(ARRAY, DIM[, MASK]) 
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 OR of all elements in ARRAY is returned. Otherwise, an array of rank n1, where n equals the rank of ARRAY, and a shape similar to that of ARRAY with dimension DIM dropped is returned.
