|
0.0000
|
|
|
X
|
0.2000
|
|
|
|

Pressing

CLX now clears the X-register (display). Notice that

Editing Display Entries

lets you ‘‘back up’’ when you have made an error. Simply
stated, any time you make an error and you want to remove numbers of ALPHA
characters (ALPHAs) you keyed in, or numbers left by a function, press
.

|
|

If the _ (underscore) prompt follows any ALPHA string or number in the display,
you can delete one character or digit at a time from that string or number by
pressing . If the _ prompt does
not follow the displayed ALPHA string or number, pressing
clears the display.

|
|
While you are keying in numbers in normal mode, pressing

a time. clears the display to zeros
if you delete all of the numbers in the display.
|

For example, key in a number, edit it, and then delete it entirely using
. Note the movement of the _ prompt.
