Understanding Action Diagram User Points

Each function type that includes an Action Diagram contains protected control logic and a set of user points unique to the function. CA 2E restricts modification of the function’s logic to these user points. It is essential that the user know the consequences of any logic that is specified in the user points since it has a direct bearing on the performance and functionality of the function.

The following information includes examples of the types of logic appropriate for various user points.

Many of the user points are self-explanatory and the user will know intuitively what type of processing should be specified. The following information is intended for illustrative purposes only. This information is meant to serve as a guide to aid the user in deciding where to insert function logic as well as what type of logic to insert to affect a certain type of functionality.

For more information and a flowchart for each CA 2E function showing its basic processing and its user points, see this module, Appendix A, "Function Structure Charts."
