Pressing the CLEAR key blanks every character position on the
face of the screen, establishes an unformatted display, and
positions the cursor to the first character position on line 1.
Your display station signals the computer program, informing it
that the CLEAR key has been pressed. While this signaling is
taking place, the INPUT INHIBITED indicator comes on, making
your keyboard inactive. Most programs will reply to the signal by
turning off the indicator. This, however, is up to the program.
Therefore, the INPUT INHIBITED indicator may remain lighted
after a CLEAR key depression. In this case, press the RESET key
to turn off the indicator. The User's Guide for the program with
which you are working will explain that program's response to a
CLEAR key depression.
Press the E RASE I NPUT key to blank or erase all input fields on
your screen. If you have a permanently displayed document on
the screen, for example, as shown in Figure 3 (page 9), and
your job is to fill in the blanks, all those areas in which you can
enter data will be erased. The cursor will also move to the first
character location in the first field in which you can begin keying
input data.
Pressing the E RASE I NPUT key while working with an
unformatted screen erases all character locations and moves the
cursor to the first character location on the top line of the
screen.
Pressing the ERASE EOF (Erase End of Field) key erases or
blanks character positions in the input field in which the cursor
is located. All character positions from the cursor location to the
end of the field are erased. The cursor, however, does not move.
A possible use of this key can be shown by supposing that
you have entered wrong information when keying in a field. You
would press the Back Tab key to return the cursor to the
beginning of the field, press the ERASE EOF key to erase the
incorrect information, and then key in the correct information.
