| 4.6 Edit the 
              Run Program Action
              To invoke the batch file instead of BroadcastByPhone program, 
              we'll need to change the run program action defined at the 
              beginning of this lesson. 
              Edit Action 
              Select Message OK element, click the properties button on 
              the program toolbar, select the Action tab. Select the 
              Run Program action, click the Edit button. 
               
              Change the program to: C:\Call List\runvcast.bat and 
              argument to '"' + message_file + '"'. Click OK to save. 
              Run the Batch File 
              When this action is executed, it will run the batch file 
              C:\Call List\runvcast.bat with the actual value of 
              message_file as the first argument. 
                
              "C:\Call List\runvcast.bat" 
              "<value of variable message_file>"
