[. . . ] To enter a space, simply press the Space bar. Each time you press the Space bar, one space is inserted on the display line. The Ins and Del keys are used to insert or delete one character at a time on the display where the cursor is positioned. When the Ins key is pressed once, it will be in insert mode. All characters to the right of the cursor position will be shifted one character to the right to make room for the new character once it is inputted through the keyboard. Pressing the Ins key again will return to the overwrite mode. New characters will overwrite the characters to the right. The Del key is used to delete one character at a time. The Del key will shift all characters to the right of the cursor one position to the left, thereby erasing the character under the cursor. Before anything on the display is actually sent, you must press the Enter key. This key acts much like a Return key on a typewriter. Don't forget to press the Enter key after typing RUN. The program that you have typed into memory will begin. The results appearing on the LCD display will be the message: HI THERE. Enter the following (no line number in front): PRINT "HI THERE" press the Enter key This time PRINT was used as a command and the results appeared immediately on the display after the Enter key was pressed. The computer executes the command right away, without waiting for you to type RUN. When you do this, the statements are not saved for future re-use. They are executed immediately and discarded. This is not recommended for creating programs but highly recommended for use as a calculator. Here are some other commands that can be used: NEW This command clears the memory of any BASIC statements that have been previously entered. 31 LIST This command displays each line of your program starting with the lowest line number. Each time you press Enter, the next lines are displayed. You can stop this by pressing the Shift and Break keys. [. . . ] After losing 3 lives, the game will end.
