HP ALLBASE/4GL Developer Administration Manual

Selecting Menu Items 

HP ALLBASE/4GL accepts input from the terminal using the MPE/iX format
mode.  This means that HP ALLBASE/4GL does not process any of your input
until it receives a carriage return or tab character.  Keep this general
rule in mind as you use HP ALLBASE/4GL menus and data screens.

When HP ALLBASE/4GL initially displays a menu, the first item is
highlighted.  To activate the highlighted item, press Return or press the
Activate Item function key.  HP ALLBASE/4GL then executes the selected
item.

You may use any of the following methods to select another item:

   *   Use the Tab key to select the item you want:

              - The Tab key selects the next item in the tabbing
              sequence, which is from left to right, top to bottom, with
              screen wrap-around from bottom right to top left.

              - Pressing Shift and Tab together followed by Return 
              selects the next item in the reverse tabbing sequence.
              Reverse tabbing sequence is from right to left, bottom to
              top, with screen wrap-around from top left to bottom right.

   *   Use any combination of the cursor control keys cursor left cursor 
       right cursor up and cursor down followed by the Return key, to
       select the item you want.  As you press the cursor keys, the
       cursor moves about the screen.  When you press the Return key, HP
       ALLBASE/4GL selects the menu item closest to the new cursor
       position.

              - The cursor home key, followed by the Return key, selects
              the top left item on the screen.

              - Pressing Shift and cursor home together, followed by the
              Return key, selects the bottom right item on the screen.

   *   HP touchscreens:
              - Touch the item you want.  HP ALLBASE/4GL responds to this
              request immediately and highlights the item.

   *   Type a selection abbreviation:
              - To select a menu item by abbreviation, enter the first
              letter of the menu item title.  A single character display
              field at the bottom left corner of the screen echoes the
              character you type.  When you press the Return key HP
              ALLBASE/4GL highlights the item corresponding to the
              abbreviation.  If there is more than one item with the same
              abbreviation, enter the same letter again and press the
              Return key.  HP ALLBASE/4GL highlights the next item
              corresponding to the abbreviation.

The following example demonstrates how to select menu items for a
particular menu.  In this example the menu is the Utilities menu.


          Utilities Menu 

When HP ALLBASE/4GL first displays this menu, the first line of the menu,
Print Administrator Documentation, is highlighted.

You can select the other items on this menu by entering the following
abbreviations:

   *   Type A Return to select Administrator Deletions.

   *   Type U Return to select Unload Application.

   *   Type L Return to select Load Application.

You cannot select any items in the main menu.  You may only select items
in the active menu.

Executing Menu Items 

You can only execute the currently highlighted menu item.  To execute the
highlighted menu item, press the Return key, or the  Activate Item  
function key.
