Rational Programming Patterns

The Screen editor

In this editor, you enter all the characteristics of a Screen.

Note: To indicate work areas, you must use micropatterns directly in the generated COBOL file.
You can simulate a Screen to check the position and characteristics of its fields and labels as they will be displayed when the transaction is run.
Important: If Rational® Programming Patterns is installed on top of Rational Developer for AIX® and Linux, you must first start a 3270 emulator. In the connection parameters, enter the IP address of the local workstation (localhost or 127.0.0.1) and the port number 8889.
From a Screen whose editor is open and selected, click Open the emulator on the selected Screen in the toolbar to open the simulation.
  • If you are in a Rational Developer for AIX and Linux environment, the Screen emulator view opens.
  • If you are in a Rational Developer for AIX and Linux environment, the simulated Screen opens in the 3270 emulator that is already open.
If you add a Data Element in the -CE Lines or change a presentation label, for example, you can see the modification in the Screen emulator view or the 3270 emulator by clicking Open the emulator on the selected Screen again.
Note: You can link the Screen emulator view or the 3270 emulator with the current Screen by clicking Link with current Screen in the view toolbar. The view or the emulator then listens to the modifications in the -CE Lines and display them simultaneously.
