When to Use a Designer-Added Procedure

The following examples detail when you can use a designer-added procedure:

• To add a menu procedure in an online environment
• A menu procedure gives the user a way to navigate through the process-implementing procedures in the business system
• For example, the menu screen in the following screen allows selection among three procedures, each of which implements an elementary process

                  Order Entry Menu                                             
                                                                               
                  1.  Take An Order                                            
                                                                               
                  2.  Delete An Order                                          
                                                                               
                  3.  Correct An Order                                         
                                                                               
                  Select Option ===> ____________________                      

• The menu window allows the same choices. The menu procedure that supports the display has no direct relevance to the business and so would not have been identified during analysis. In this case, the designer has added the procedure simply to improve the system flow
• To create a report or display, in which data is presented to the user, but is not manipulated for any single business purpose
