Chapter 12: The SOLVER Feature

2. Saving/Renaming Equations for Later Use

The expressions you have entered in the SOLVER can be named and stored:

1.Go to the SOLVER menu by pressing @'.

2.Press Cto select the C SAVE menu, and press

E.

3.When the next screen appears, ALPHA LOCK mode is automatically set and the cursor is changed to “A”, indicating that alphabet characters can be entered.

To enter numbers, press A.

The equation name should consist of 8 characters/numbers or less.

4.When done, press E. The screen goes back to the SOLVER function screen.

Saved SOLVER expressions can also be renamed:

1.Go to the SOLVER menu, and press Dto select the D RENAME sub-menu.

2.A list of saved equation names appears in the sub- menu. Select the equation name you wish to change. For example, press 0 1to select the first item of the list.

3.When renaming is complete, press Eto save the change. The screen goes back to the SOLVER function screen.
