Expanding and collapsing the Variables view list

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.

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.
