* To better understand this example you should be famililar with the shipped Personnel System demo.
*
* We expect the following screens to appear as part of this navigation:
*
* Login -> type in user and password -> press Enter -> (a special screen? <F3>)
* i5 Main Menu -> type lansa run process(pslsys) partition(dem) -> press Enter
* Personnel System -> type option 3 -> press Enter
* Inquire -> type the current instance employee number -> press Enter
* Browse Employee Details and Skills in OUTPUT mode -> press F21
* Browse Employee Details and Skills in INPUT mode

* The Payload is a 256 character string sent together with a SENDKEY. Use the Payload in the same way you would use parameters in an event.
* Assuming when 'updempskills' arrives we change some details and press Enter or click on the SAVE button, we expect one of these 2 screens to appear:
* If the SAVE was successfull, the INQUIRE screen appears.
* If the SAVE was NOT successfull, the update employee screen will reappear
* Setting the Payload we determine what caused the screen 'updempskills' to arrive.
*
* 1. In the Button script of updempskills for the Enter key, we attach a payload = "UPDATE_EMPLOYEE":
*
* case KeyEnter:
* SENDKEY( KeyEnter, "UPDATE_EMPLOYEE" )
* break
* 2. In the ARRIVE script of INQUIRE, we test payload. If the Payload is UPDATE_EMPLOYEE this is telling us we have just done an Update and we are most likely to want to go back to the same screen.
*
* if ( TOSTRING(oPayload) == "UPDATE_EMPLOYEE")
* {
* NAVIGATE_TO_DESTINATION("updempskills")
