Normally, screens in Lookup or Delete mode, for both Paging and non-Paging Screens display data only. Paging Screens in Delete mode wait for the user to select and confirm the lines to be deleted. Non-Paging Screens in Delete mode display the ‘Are You Sure?’ prompt. Previously, it was not possible in these modes to view underlying screens. It is now possible to flag Screen field variables to allow access to them during Lookup and Delete mode. This feature is called Augmented Display Mode. When Augmented Display mode is set, those fields become windowable in Lookup and Delete modes.
When a screen is in Lookup or Delete mode and some screen fields have been marked for Augmented Display, the following applies:
In non-Paging Screens, the cursor is positioned at the first field flagged for Augmented Display.
In Paging Screens, you enter Augmented Display mode explicitly by pressing the Lookup Function Key.
You can enable the Augmented Display mode in the Behaviour tab of the relevant Screen Properties window by checking the Accept Focus in Lookup check box option. Click here to view a screenshot of the Accept Focus in Lookup check box.
You can suppress the Augmented Display mode in Delete mode by selecting the Augmented Access check box in the Suppress section on the Behaviour tab in the Screen Cycle Properties window. Click here to view a screenshot of the Augmented Access check box.
In general, the cursor movement keys do what they would do in Change mode except they only stop at fields that are specified as Augmented Display fields. The following actions should be noted:
|
Item |
Description |
|
Enter or Return |
The cursor moves to the next Augmented Display field, moving through fields in field order. |
|
Arrow keys |
In non-Paging Screens, the cursor moves to the nearest Augmented Display field in the direction of the arrow. In Paging Screens, the up and down arrows move the cursor to the previous or next record, for the same field. |
|
Tab |
The cursor moves to the Augmented Display field that is the next tab field or follows the next tab field. |
You can exit from Augmented Display mode by pressing EOD, CANCEL, or <Return> until the last Augmented Display field has been passed.
Marking a field for Augmented Display is subject to the following restriction:
Fields marked for No Change or Display Only cannot be marked for Augmented Display.
When Augmented Display is in effect, the system behaves as follows:
When the cursor is positioned on an Augmented Display field, only the Window Function Key is allowed. The associated screen is in Lookup mode when displayed.
When a field is visited in Augmented Display mode, the before field logic is executed. Processing waits for user input and if the WINDOW Function Key is selected, the window associated with the field is opened. When the window is closed, processing waits again for user input. Special Check and General Check logic will not be executed. When the user exits the field, the after field logic is executed and files associated with the field, if any, are read and their logic executed.
When a field is automatically skipped because it is not an Augmented Display field, it will be processed as if it is skipped by tabbing, that is, the before field logic, special check logic, and general check logic will not be executed, but the after field logic and file reads will be executed.
The cursor will not stop on any field that it would not have stopped on if the screen were in Change mode.
Field input is not allowed in Augmented Display mode.
