Where it can save screen displays and so be efficient for the user dialog, it is possible to provide some import data directly from the TRANCODE or other field of a previously displayed screen. In the case of an external procedure, some output can be matched with the import view.
This can be done using Clear Screen Input, but only for the first step of a procedure.
Note: The Clear Screen Input feature of CA Gen is described fully in the Toolset Help.
The CA Gen Dialog Manager automatically populates the import view for the destination procedure, but a procedure that can be initiated in this way may need to test the command to determine whether this situation has occurred.
Before the last display of the screen during the execution of a transaction, a procedure step can populate the TRANCODE field with the command and required data value. The required data value is usually a key that will steer the execution of the following process. This will give the user the option to transfer directly to the procedure of another screen. The user then needs only to press the Enter key to proceed.
