size(3I)

NAME
     SIZE - Returns the total number of elements in an array

SYNOPSIS
     SIZE ([ARRAY=]array [,[DIM=]dim])

STANDARDS
     Fortran

DESCRIPTION
     The SIZE intrinsic function returns the extent of an array along a
     specified dimension or the total number of elements in the array.  It
     accepts the following arguments:

     array     May be of any type.  It must not be scalar.  It must not be
               a pointer that is disassociated or an allocatable array that
               is not allocated.  If array is an assumed-size array, dim
               must be present with a value less than the rank of array.

     dim       Must be scalar and of type integer with a value in the range
               1 <= dim <= n, where n is the rank of array.

     SIZE is an inquiry function.  The name of this intrinsic cannot be
     passed as an argument.

RETURN VALUES
     The result is a default integer scalar.  The result has a value equal
     to the extent of dimension dim of array or, if dim is absent, the
     total number of elements of array.

EXAMPLES
     SIZE(A(2:5,-1:1),DIM=2) yields 3.

     SIZE(A(2:5,-1:1)) yields 12.
