    Answers:

    A subscript is a working storage data definition item, typically a PIC (999) where a value must be moved to the subscript and then incremented or decrements by ADD TO and SUBTRACT FROM statements. An index is a register item that exists outside the program?s working storage. You SET an index to a value and SET it UP BY value and DOWN BY value.
