Closing an input form

An input form might be used to make global changes—for example,

changing the date or time—or to set up the parameters for some other

operation (such as setting the coordinates for plotting a particular

equation).

If your input form will change global settings, press OK. This saves your

settings and closes the form.

If your input fonn is designed to record the parameters for some further

operation, a menu key is displayed representing that fm-ther operation.

(For example, the input forms for plotting a graph will display a menu

item labelled draw. Pressing the corresponding fimction key causes the

equations specified to be drawn according to the parameters specified on

the input forms. (See chapter 4, “Plotting graphs” for more information on

plotting.)
