The PC-2 can produce sounds with the BEEP statement. You must specify the number of beeps. You can also
specify the frequency and duration (e.g., the length of each beep).
The frequency can range from 7kHz (0) to 230 Hz (255). This means that each unit of measurement between
0-255 is equal to about 2605Hz. When you do not specify frequency, the PC-2 uses 8 (approximately 4 kHz.)
