Screen List Selector
With a Screen List Selector, the operator presses Up Cursor and Down
Cursor buttons to scroll through a list of screen names, then presses the
Enter button to switch to a selected screen. The Screen List Selector is
similar to the Control List Selector with Enter, but it is only used to control
screen changes.
The Screen List Selector consists of the following components:
List is a vertical list that can contain up to 24 different items (12 with
double sized text). If you include a border around your list you will lose
two single size or one double size entry.
The operator presses the Up Cursor or Down Cursor buttons to move
the arrow indicator up and down through the list. When the Enter
button is pressed the screen is selected.
Up Cursor button moves the arrow indicator up one entry.
Down Cursor button moves the arrow indicator down one entry.
Enter button selects the desired screen, and makes the screen appear.
Use Buttons in the Object Menu to configure the Up Cursor, Down Cursor
and Enter buttons in your Screen Selector. To save screen space you can
disable either the Up Cursor or the Down Cursor button (but not both). A
button that has been disabled doesn’t appear on the screen.
Choose List in the Object Menu to configure the selector list.
Use Move to position your object on the screen.
Choose Width to specify how many characters you can fit on a line for
each state in the list.
Choose Number of States to define the height of the list. For single height
characters, you can have up to 24 states; for double height characters you
can have up to 12 states.
