To Disable Portions of the Menu System

Using the following steps, you can disable specific pads, popups, or bars of popups in a menu system.

NOTE: This procedure can be used in conjunction with or instead of a READ MODAL command.

1. In the Menu Builder, create the menu system.

2. Select the item you want to disable.

3. Select the Options box. In the Prompt Options dialog box, select the Skip For check box, and type the following as the Skip For expression:

         RDLEVEL()>1
   

   NOTE: If the application is not controlled by a foundation READ, the expression should be:

         RDLEVEL()>=1
   

4. Repeat steps 2 and 3 for every item that needs to be disabled.

To Disable the Entire System Menu

NOTE: This procedure can be used in conjunction with or instead of a READ MODAL command.

1. Create the screen you want to combine with your menu system.

2. Add a WHEN clause to the READ command. It should be marked as a Procedure and contain the following command to disable the system menu:

          SET SKIP OF MENU _MSYSMENU .T.
   

3. In the screen's Cleanup code, add the following command to activate the system menu again:

         SET SKIP OF MENU _MSYSMENU .F.
