Summary In this lesson you created a function. The function is executed as an after function for the product_no screen field, and performs a file lookup after the user enters data in the field. There are three steps involved in developing a function. They are: 1. Define the function header. 2. Define the function details. 3. Generate the function. If you are developing the KSAM based application or the HP TurboIMAGE/iX based application, you have completed all the logic you need for now. Turn to the Self Test Questions at the end of this chapter. In Chapter 5, you can start testing the application. If you are developing the HP ALLBASE/SQL based application, complete the next lesson to create the SQL logic blocks called by the product_proc process and the product_key_read function.
