Buffers, temp tables, datasets, class variables, arrays, and properties of a class type have subordinate elements (fields or tables), which in turn may have subordinate elements of their own (for example, an array index). These hierarchical elements appear in the Variables view with a plus symbol (+) before the name.
• To open the Variables view if it is not open select Window > Show View > Debug > Variables.
• To expand the hierarchy and show the subordinate values, click the plus symbol (+).
• To collapse the hierarchy selectively, clicking the minus sign symbol (-);
• To collapse all entries and show only top-level data elements, click the Collapse All on the toolbar.
Note: Any object reference or handle that has not been initialized cannot be expanded. Arrays, buffers, and temp-tables can be expanded, whether initialized or not.
