Invoke Script

Every [Destination Screen] has an invoke script which controls how it is displayed. Here is an example of a script that invokes a SHOWORDER screen when an order is selected in the instance list:

First the script navigates to the 5250 junction screen GETORDER which is used to select which order is to be shown:

NAVIGATE_TO_JUNCTION("GETORDER");

It then makes sure that we get to the GETORDER screen. If this check fails an error message is shown:

if ( !(CHECK_CURRENT_FORM("GETORDER", "Unable to navigate to form GETORDER")) ) return;

Next the script retrieves the current order number from the instance list to the GETORDER screen. Typically you need to edit this part of the script (see [Replacing Hardcoded Employee Number with Current Instance List Entry]):

SETVALUE("ORDERNUMBER", objListManager.AKey1[0] );

And then presses the Enter key to process the GETORDER screen:

SENDKEY(KeyEnter);

Finally the script makes sure that screen SHOWORDER has arrived back from the IBM i and is ready to be displayed. If this check fails, an error message is shown:

if ( !(CHECK_CURRENT_FORM("SHOWORDER", "Unable to display order number " + objListManager.AKey1[0] )) ) return;
