Linking Menu and Application Screens
12–2
Menu and sub-menu links provide one way links with up to 8 application
screens or sub-menus. An operator selects a menu item by pressing the
numeric key corresponding to the menu item. When you link the main
menu and sub-menu items you are linking screens to the keys on the
numeric keypad.

The following rules apply to linking screens:
•
Only screens that are already defined can be linked.
•
Wait until you have developed all of your screens and menus before
establishing links. It is much easier to create your links once, rather than
change them whenever you change the order of screens.
•
A non-menu screen cannot be linked back to a menu screen, use a Goto
(one way) link instead.
•
A link is a one-to-one relationship between the current screen and the
target screen. You cannot establish more than a single one-way link to
any particular screen.
If you attempt to link to a destination screen that is already linked, you
have the option of inserting the screen (changing the current link) or
aborting the operation.
