The SummationSqrArray function only works with one-dimensional arrays.
The first element of the array that is used by this function is element 1. Element 0 of the array is not used.

The following assigns the summed squares of elements 1 to 20 of myArray to the pre-declared variable Value1 (element 0 of myArray is ignored):
Array: myArray[20](0);
{… add EL statements here to assign values to array elements... }
Value1 = SummationSqrArray(MyArray, 20);
