SOUND Statement Details
 
Syntax
  SOUND frequency,duration
 
The frequency is the desired frequency in hertz (cycles/second). It must
be a numeric expression returning an integer in the range 37-32,767.
 
The duration is the duration in clock ticks. (There are 18.2 clock ticks
per second regardless of CPU speed.) The duration must be a numeric
expression returning an unsigned integer in the range 0-65,535.
 
If the duration is zero, any current SOUND statement that is running is
turned off. If no SOUND statement is running, a SOUND statement with a
duration of zero has no effect.
