Before creating the application, you must identify its purpose, decide on which graphical elements to include, and figure out which JSL scripts you need to write.
Purpose
What do you want the application to accomplish? Which features of JMP do you need to customize (for example, a launch window, report, or graph)?
Graphical Elements
How many modules do you need? Look at the list of graphical objects in Application Builder and decide which objects to include in your application. The Sources panel shows dozens of boxes and icons that you can drag and drop into a module. Also look at the preinstalled samples to see whether a similar module exists.
Scripting
Depending on the complexity of the application, you write JSL scripts. See Write Scripts for more information about writing scripts for an application.
A non-interactive application that only shows objects does not require scripts. One example is a window showing reports that you have already generated in JMP.
