The Ext Code can be up to 5-digits long depending on the Ext 
Len field entry. The entry cannot be greater than the Ext Len 
field entry. For example, in the case of a 4-digit Ext Len field 
entry, an Ext Code of 12 is the equivalent of all extensions of 
the screen 12xx, excluding any explicitly listed longer codes. 
If a code of 123 is also listed, the 12 code is equivalent of all 
extensions of the screen 12xx except extensions of the screen 
123x. The coding precludes having to list all the applicable 
12xx extensions.
