Default Action Diagram

CA 2E supplies a default action diagram for each function. An action diagram contains the processing steps that make up a function. Each action diagram consists of a list of actions, where each action may be either a call to another function or one of a number of low level built-in functions.

To view and edit the default action diagram for the Edit Horse function, from the Edit Function panel enter F in the Subfile selector for the Edit Horse function as shown in the following example:
