The SUM function returns the sum of all the elements in the array.
If the elements of the array are strings, they are converted to fixed-point values. If they are neither fixed-point values
nor strings, they are converted to floating-point values. In the latter case, the result is a floating-point value; otherwise,
it is a fixed-point value.
Examples
DECLARE (A(4), I) FIXED BIN (15);
DO I = 1 to 4;
A(I) = 4;
END
I = SUM(A); /* returns 16 */
