GENERAL INFORMATION
11. Edit Modes
Expressions can be entered either by the one-line input method or the equation input
method.
In the one-line edit mode, the EL-9650 is used in the same way as a standard scientific
calculator. The equation edit mode allows entries of fractions and functions such as
powers, roots and constants in a straightforward sequence. (Matrices cannot be
entered in a straightforward sequence.)
To set a mode, select : [Equation] (equation edit mode) or [One line] (one-line edit
mode) by using [G EDITOR] of the SET UP function.
If an expression has been already entered and is displayed, the expression cannot be
changed by switching the input mode.
(If the EDITOR setting is changed in the middle of entering an expression, the portion
of the expression that has been entered will be deleted.)
* The calculation speed of the equation edit mode is slower than that of the one-line edit mode
due to extra internal processing.
(1) Equation edit mode
Expressions are displayed two-dimensionally in commonly used mathematical expres-
sions.
In the equation edit mode, expressions up to 114 bytes can be entered and the display
shows up to 8 lines of an expression and a calculation result. (It is not possible to input
an expression exceeding this limit.)
In the equation edit mode, each key input is displayed after the calculator completes
the internal processing to locate the display position of the variable or function. There-
fore, the calculation speed is slightly slower. The calculator memory retains a maximum
of three keystrokes. Therefore, keys may be operated before the input of the previous
keystroke is displayed on the screen. (The screen may display several entries all at
once.)
To enter an expression, use number keys, arithmetic keys, other function keys and
cursor keys (<>≥≤).
The following functions are displayed two-dimensionally on the display.
