Sharp EL-9900 operation manual Value

Chapter 13: Programming Features

•The commands and functions in the VARS menu can be displayed on the screen. Current setting data can also be reset.

•The results of arithmetic functions can also be displayed.

•The ZOOM command is selected directly from the ZOOM menu. Names of some ZOOM commands change when inserted into programs. These are [A ZOOM], [C POWER], [D EXP], [E TRIG], and [F HYP] of the ZOOM menu.

“Zm_” is automatically added to each of these functions when inserted into programs.

Example

Zm_Auto, Zm_x2, Zm_sin, etc.

•Always enter the argument for functions requiring an argument at the end of the command, such as the CALC function (@ k). An error will be returned for commands not accompa- nied by an argument.

Example

Value 5

Example

Set Xmin = -3, Xmax = 10, Xscl = 1, Ymin = -5, Ymax = 5, Yscl = 1 in the WINDOW screen.

Use Rto input the settings.

Expression		Operational sequence
-3 ⇒ Xmin		_3		R@zBEA1E
10 ⇒ Xmax		10 R@zE2E
1	⇒ Xscl	1	R@zE3E
-5 ⇒ Ymin		_5		R@zE4E
5	⇒ Ymax	5	R	@zE5E
1	⇒ Yscl	1	R	@z E6E

*Operation to input a function equation (for example, x2 + 2) to the graphic equation “Y1” is also made using Rin the same manner as described above.

“X2 + 2” ⇒ Y1: PA2Xy+2 P A2R@zAEA1

Note: Function equations cannot be assigned in the graphic equations, such as Y1, if the EDITOR mode under SET UP is set to Equa- tion. Switch the EDITOR to One line mode prior to assigning such
