Try this:

FUNCTION Beep
LPARAMETERS nFrequency, nDuration

  IF EMPTY(nFrequency)
    nFrequency = 1000
  ENDIF

  IF EMPTY(nDuration)
    nDuration = 40
  ENDIF
	
  DECLARE Beep IN Win32API INTEGER dwFreq, INTEGER dwDuration

  =Beep(nFrequency, nDuration)
	
RETURN

>I am trying to make the internal PC speaker beep by issuing ?? CHR(7). It does not seem to work for me. My PC has a soundcard (or perhaps its built into the MB) but I don't have external speakers attached so I want to use the internal one.
