You can specify how many levels of the hierarchy you want
to see by selecting a level from the list on the module toolbar. Objects
that are lower in the hierarchy than the level you have selected are
hidden.
About this task
You can also use outlining to show only objects that have
object heading, and compression to hide sections of the hierarchy.
When
outlining is on, you only see objects that have a heading and only
the Object Heading of those objects is shown. You can use outlining
in document mode or in graphics mode.
Note: Outlining only affects
what is shown in the module window. The Module Explorer always shows
all the objects in the current view.
When outlining is turned
on, you can compress parts of the hierarchy. A plus sign indicates
that objects are hidden.
