Describing Lists and Arrays

Once a list or array is populated, you can use the describe menu choice to display its elements, or to display the lists and arrays to which an item belongs. The Describe facility includes a list or array index for every VALUE-ARRAY element.

The next diagram shows an example of the Describe facility for an array and a list. The description of the list contains short references to the variables that are its elements.


When you select describe from the menu of a list or an array, G2 displays a workspace containing information about every datum or item in the list or array. Click on the short reference of the element item to access the attribute table of the original, go to the original item, and so on.

The Describe display does not update dynamically as list or array elements change.


Note: We do not recommend using the Describe facility for very long lists or arrays with many elements, because it uses a large amount of storage space.
