Pushbuttons or Function Keys in Dialog Boxes 

Pushbuttons should be lined up across the bottom of the dialog box:

·

ENTER=<ACTION>

(always the first button)

 

FX=SPECIAL FUNCTIONS

(ascending order)

 

F12=CANCEL

(the last developer-definable key)

 

(In this order)

  

must always be displayed. Abbreviations are allowed (see Abbreviations).

Executing Dialog Boxes

Executing a dialog box (that is, activating the ENTER key) is possible via the first pushbutton ENTER=<ACTION> : normally <ENTER=EXECUTE> (see Execute (Function)), ENTER=CONTINUE (see Continue (Function)) or after pressing F4 from the primary window or for dialog boxes which contain a selection list, also <ENTER=CHOOSE> .

In this case, F2 additionally has to be reserved for Choose (Function) so that double-clicking with the mouse is also supported; F2 , however, is not displayed.) Otherwise, the function to be executed can also be referred to directly ( Copy (Function)), for example).

Exception:

Dialog boxes which contain a question are instead provided with their own pushbuttons for the positive and the negative response. The ENTER key is then not displayed. Messages from the system which have to be confirmed receive the name ENTER=CONFIRM , in the case of read-only dialog boxes, ENTER=CONTINUE (see Prompts in Dialog Boxes).

ENTER Key

The dialog box and the entries made are processed if the user presses the ENTER key. Then, the system either returns to the previous primary window or navigates to a new one or another dialog box is displayed (in this case the previous dialog box remains on the screen).

F12 =Cancel

If F12=CANCEL is pressed, the dialog box disappears and the program either returns to the primary window or to the last dialog box (even if the dialog box contains required entry fields).

If possible, the previous status is fully restored - that is, the entries are "forgotten" and any processed entries are cancelled.

In extraordinary circumstances, if the entries can no longer be cancelled, either a dialog box is displayed with a warning that certain processing steps have already been carried out, or an error message is displayed in a dialox box informing that the "Processing step cannot be cancelled completely". To leave the processing, the user has to press ENTER . F12 returns to the last processing step.

Read-only dialog boxes or dialog boxes displaying information are an exception. F12=CANCEL is actually reserved here, but it is not displayed.

F1 =Help

F1 is always active and is associated with individual fields, as in the primary window. Whether F1 is displayed in the application toolbar depends on the global configuration and cannot be influenced by the developer; F1 is currently not displayed.

F4 =Possible Entries

F4 is not displayed in the application toolbar.

After pressing F4 , another dialog box is displayed (the first remains where it is) with the respective possible entries.

F3 =Back, F15 =Exit

In dialog boxes, F3 and F15 are not allowed . Dialog boxes are side paths which can only be cancelled with F12 .

Save

Saving via F11 is not allowed in modal dialog boxes . The Save or Post action always has to be carried out in a primary window. If a dialog box with a confirmation prompt (for example, after pressing F15=EXIT ) of the lines Should data be saved? is displayed, the user can save by answering in the affirmative. However, data cannot be directly saved with F11=SAVE .
