Screen Navigation Within a
Pathmaker Application
One important aspect of any application is how it allows the end user to navigate
among screens. The Pathmaker product produces applications that have a
hierarchical structure.
In an application with a hierarchical structure, the application's requesters are
arranged in a fixed hierarchy, sometimes referred to as a tree. Typically, this hierarchy
has a main menu requester at the top level with submenu requesters below leading to
detail requesters (used for data entry or data retrieval) at the lowest levels.
When using an application that has a hierarchical structure, the end user navigates
between requester screens and related business tasks by pressing a function key once
for each step up or down in the hierarchy.
