Subscripting Using Integers or Data-Names
When an integer or data-name is used to represent a subscript, it can be used to reference items within different tables. These tables need not have elements of the same size. The same integer or data-name can appear as the only subscript with one item and as one of two or more subscripts with another item. A data-name subscript can be qualified; it cannot be subscripted or indexed. For example, valid subscripted references to TABLE-THREE—assuming that SUB1, SUB2, and SUB3 are all items subordinate to SUBSCRIPT-ITEM—include:
ELEMENT-THREE (SUB1 SUB2 SUB3)
ELEMENT-THREE IN TABLE-THREE (SUB1 OF SUBSCRIPT-ITEM, SUB2 OF
SUBSCRIPT-ITEM, SUB3 OF SUBSCRIPT-ITEM)
