Program Command Reference

GetPen

Syntax: GetPen￿<variable name 1>, <variable name 2>

Function: This command assigns the coordinates of the point tapped on the screen to a specified variable.

Description

This command assigns the x-coordinate (horizontal axis) to <variable 1> and the y-coordinate (vertical axis) to <variable 2>. The coordinates at the point in the upper left corner of the screen are (1, 1), and coordinate values are specified in the range of 1 to 160 for the x-coordinate and 1 to 240 for the y-coordinate.

Input

Syntax: Input￿<variable name>[,"<string 1>"[,"<string 2>"]]

Function: When program execution reaches the Input command, the user is prompted for input of a value, which is assigned to the specified variable.

Description

•If you do not specify anything for "<string 1>", the prompt “<variable name>?” appears by default.

•The text specified for "<string 2>" is used as the input dialog box title.

•The Input command pauses program execution and displays a dialog box that contains the text string indicated by "<string 1>" and an input box. A text string enclosed within quotation marks (" ") or a variable name can be specified for "<string 1>".

•Specifying a long text string can cause part of it to be cut off when it is displayed in the dialog box.

•When the dialog box appears, input a value into the input box and then tap [OK]. This closes the dialog box, assigns the input value to the applicable variable and resumes program execution.

•Tapping [] on the dialog box terminates program execution.

•During execution of the Input command, program execution is paused for input of data. While a program is paused, you can input individual mathematical expressions only. You cannot input commands or multiple expressions joined by colons (:).
