Question

On the initial report display screen, only the carrid, connid, cityfrom, and citytofields should be shown. When the user double-clicks on any record displayed in the initial report display screen, a new detail screen should appear which displays the associated fltime, deptime, arrtime, airpfrom, and airpto fields.The layout of the detail screen is up to you, but make it look nice. If the user attempts to double-click on the detail report, an error message and banner should be displayed at the bottom of the screen notifying the user that no further details are available. Finally, the original program displays an error if an incorrect carrid is entered, or if no matching flights can be found. Change the program so that these errors are also displayed using banners at the bottom of the screen.

I need to modify the following program with the above instructions, the language is APAB - SAP.
