Window hierarchies

The relationships between windows are important when you execute certain commands. For example, when you remove a window, you can either remove the window alone or remove the window and its descendant windows. This section shows you how to determine a window’s current relationship to other windows.

In the upper-right corner of each window is a level number that indicates its place in the window hierarchy. When you open another window, that new window is a descendant. The window from which it was generated is the parent window.

The first Main Menu is always level 1. All other level numbers are two digits in the form x.y, where x is the sequence number and y indicates its parent window.

For example, the first descendant of the Main Menu is always 2.1: the 2 indicates it’s the second window opened. The 1 indicates the parent window’s sequence number (level 1). If you generate a window from 3.1, its level is 4.3. The following figure shows several more examples.
