When a reference to a paragraph or section is selected,
you can select the Open Perform Hierarchy action
from the pop-up menu.
The
Perform Hierarchy view displays the
paragraphs and line numbers for each statement in the hierarchy and
allows you to easily navigate among those statements. The
Perform
Hierarchy view has the following two modes:
- Performer Hierarchy.
- Performee Hierarchy.
The
Performer Hierarchy displays the references
to the selected paragraph. For example, given the paragraph "Copy-input-to-output,"
the
Performer Hierarchy displays all paragraphs
and sections that can transfer control to that paragraph with a statements
such as
Perform Copy-input-to-output. The
Performee
Hierarchy displays the references to other paragraphs
contained within the selected paragraph. For example, given the
Copy-input-to-output paragraph,
the
Performee Hierarchy displays a statement
that can transfer control outside of the selection paragraph with
statements such as
Perform Read-next-input-data.
Because perform hierarchies can be nested arbitrarily, the
Perform
Hierarchy is a tree view that lets you traverse this nesting.
This is an example of the Performee Hierarchy.
