Initially, the designator characters in most
of
the selection fields on your screen
will be question marks. To select an item (field), position the cursor within the
selection field
that
you
want
to
select; then press the CURSR SEL key. The
question mark
at
the beginning
of
the selected field changes
to
a greater-than
sign
to
indicate
that
the field has been selected.
If
you
select the wrong field,
you
can correct your mistake
by
selecting the field
again with the
CURSR SEL key. This changes the greater-than sign back to a
question mark and deselects the field. The correct field can then be selected.
After
you
have completed your selections from
the
screen (more than one selec-
tion
can be made), locate a selectable field (attention field)
that
has an amper-
sand character or a blank position for a designator character. Selecting the
attention
field turns
on
the Do Not Enter - Time (
)(
·:f
) message and indi-
cates
to
the program
that
you
have completed
your
selections. The data you
have selected can now be acted upon by the program.
The way you end a
CURSR SEL operation depends on
the
program, and each
job
could be different. Always refer to the user's program guide for the pro-
gram with which
you
are working for specific instructions.
CLEAR
Key
Pressing the CLEAR key while holding the ALT key down (1) erases or blanks
every character location
on
the screen except the Operator Information Area,
(2) establishes an unformatted display, and (3) positions the cursor to the first
location in line
1.
The CLEAR key does not change the keyboard shift status
of
your display
station, but
it
removes the NUM message in the Operator Information Area
if
it
is
on. Also,
if
you are using a 960-, 2560-, 3440-, or 3564-character capacity
display station that
is
formatted for the full screen capacity, pressing
the
CLEAR
key may cause your display station
to
be
unformatted as a 480- or 1920-
character display.
When
the
CLEAR key
is
pressed,
your
display station signals the program, infor-
ming it
that
the CLEAR key has been pressed. While this signaling
is
taking
place, the
Do
Not Enter - Time ( )( ':l ) message appears, disabling your key-
board. Most programs reply
to
the signal by turning
off
the Time message. This,
however,
is
up to the program. Therefore, the Time message may remain
on
after
a
CLEAR key depression.
If
you are not familiar with
the
program's response
to
a CLEAR key depression, ask the appropriate person in your organization about
the program's response or refer
to
the appropriate user's program guide.
