Inputting and editing coefficients

1. Rules for inputting and editing coefficients:

- Data is inserted into the cell where the cursor is

moves to the next cell on the right.

- The values and expressions you can input on the

coefficient editor screen are the same as those you can
input in the COMP Mode with Linear format.

- Press

while inputting data clears your current input.

- After inputting data, press

. This registers the value

and displays up to six of its digits in the currently
selected cell.

- To change the contents of a cell, use the cursor keys to

data.

2. You can clear all coefficients to zero by pressing the

key

while inputting values on the coefficient editor screen.

3. The following operations are not supported by the Coefficient

and multi-statements also cannot be
