Steps Required to Link Functions

In this topic, you will define a Display Racing results function and link it to the Edit Horse function. You will also update the Edit Horse function. The process is similar to that of adding a message function. To achieve the objectives for this topic you will need to:

  1. Modify the action diagram of the Edit Horse function to specify the condition under which the Display Racing results function is to be called.
  2. Define the Display Racing results function by giving it a name and type and selecting an appropriate access path based on the RACE ENTRY file.
  3. Specify the parameters of the Display Racing results function; namely, Horse code.
  4. Select the Display Racing results function for inclusion in the action diagram of the Edit Horse function.
  5. Modify the action diagram of the Edit Horse function to defer updating the HORSE file if a line selection is made.
  6. Modify the Selector Choice menu of the action bar of the Edit Horse function’s device design to show the availability of the Display Racing results function.
