Produces a beep sound.

Syntax
	KeyPgDeclareDeclare KeyPgSubSub Beep ( )
	KeyPgDeclareDeclare KeyPgSubSub Beep ( KeyPgByvalByVal duration KeyPgAsAs KeyPgSingleSingle, KeyPgByvalByVal pitch KeyPgAsAs KeyPgSingleSingle )

Usage
	Beep
	Beep duration, pitch

Parameters
	duration
		Duration in seconds.
	pitch
		Pitch as semitones from middle C, matching the sfxlib pitch form.

Description
	Beep tells the system to sound a beep noise.  The no-argument form keeps 
	the traditional console behavior.  The two-argument form uses sfxlib and 
	produces a generated note with an explicit duration and pitch.

	For more control over generated sound, use the sfxlib commands such as 
	KeyPgSfxGeneratedSound, KeyPgSfxGeneratedTone, KeyPgSfxGeneratedNote, and KeyPgSfxGeneratedPlay.

Example
	Beep

Differences from QB
	*  In QB, this was a single tone noise generated through the PC 
	  speaker. Now this might not be the case.
