Entry screens, exit screens, and transient screens
You can use the entry screen, exit screen, and transient screen settings to mark macro screens that you want the macro runtime to treat in a special way. In the Macro Editor, you make these settings on the General tab of the Screens tab. At the top of the tab, under the Screen Name field, are listboxes for Entry Screen, Exit Screen, and Transient Screen. For each of these listboxes, you must specify a boolean value (the default is false) or an expression that evaluates to a boolean value.
In the Code Editor, these settings appear as attributes of the <screen> element. In Macro screen ScreenR with <nextscreens> element, above, you can see these three attributes in the <screen> element for ScreenR: entryscreen, exitscreen, and transient.
