Making Selections
Changing Selections
To see more clearly which fields on your screen are light-
pen-detectable, press the end of the selector pen against the palm
of your hand. This will cause lines to appear through all
light-pen-detectable fields.
Initially, the designator characters (the first characters) of
most detectable items on your screen will be question marks. To
select an item, place the point of the pen directly over any
character in that item and push the pen toward the screen to
detect it. The question mark at the beginning of that item will
change to a greater-than sign to indicate that the item has been
selected. Positioning' the pen incorrectly (not directly over the
intended character or over a character in another item) can cause
the wrong item, or no item, to be selected. Therefore, you
should always verify that the designator character has been
changed after you have selected an item from your screen.
If you select a wrong item, you can correct your mistake by
selecting a character from the incorrect item a second time with
the selector pen. This will change the greater-than sign back to a
question mark and deselect the item. The correct item can then
be selected.
After you have completed your selections from the screen
(more than one selection can be made), locate a field that is
selectable but doesn't have a designator character. Selecting this
item (the word EXIT in Figure 42) turns on the INPUT
INHI BITED indicator and indicates to the program that you
have completed your selections, and the data you have selected
can no~ be acted upon by the program.
Remember, Figure 42 is only an example. The way you end a
selector pen operation depends on the computer program, and
each job could be different. Always refer to the User's Guide for
the program with which you are working for specific instruc-
tions.
