E-11
Displaying a Long Expression
The display can show up to 14 characters at a time. Inputting the
15th character causes the expression to shift to the left. At this time,
the ] indicator appears to the left of the expression, indicating that
it runs off the left side of the screen.
Input expression: 1111 + 2222 + 3333 + 444
Displayed portion:
•When the ] indicator is displayed, you can scroll left and view the
hidden part by pressing the d key. This will cause the ' indicator
to appear to the right of the expression. At this time, you can use
the e key to scroll back.
Number of Input Characters (Bytes)
•You can input up to 99 bytes of data for a single expression.
Basically, each key operation uses up one byte. A function that
requires two key operations to input (like 1s(sin
–1
)) also uses
only one byte. Note, however, that when you are inputting functions
with Math format, each item you input uses up more than one
byte. For more information, see “Inputting with Math Format”.
•Normally the input cursor appears as a straight vertical (
I
) or
horizontal ( ) flashing line on the display screen. When there are
10 or fewer bytes of input remaining in the current expression, the
cursor changes shape to
I
to let you know. If the
I
cursor
appears, terminate the expression at a convenient point and
calculate the result.
k Correcting an Expression
This section explains how to correct an expression as you are
inputting it. The procedure you should use depends on whether you
have insert or overwrite selected as the input mode.
About the Insert and Overwrite Input Modes
With the insert mode, the displayed characters shift to the left to
make room when you input a new character. With the overwrite mode,
any new character you input replaces the character at the current
cursor position. The initial default input mode is insert. You can change
to the overwrite mode when you need it.
• The cursor is a vertical flashing line (
I
) when the insert mode is
selected. The cursor is a horizontal flashing line ( ) when the
overwrite mode is selected.
• The initial default for Linear format input is the insert mode. You
can switch to the overwrite mode by pressing 1Y(INS).
