In QuickBASIC, the PLAY statement can produce a click on the speaker
for the first note of rest (but not for subsequent notes of rest). For
example, the following program will produce no sound when run under
the BASICA or GW-BASIC Interpreter, but produces a single click when
run as a compiled QuickBASIC program:

   10 while inkey$ = ""
   20 play "N0"    ' N followed by zero (0) means play a note of rest.
   30 wend

Microsoft has confirmed this to be a problem in QuickBASIC versions
2.00, 2.01 (buglist2.00, buglist2.01), 3.00, 4.00, 4.00b, and 4.50; in
Microsoft BASIC Compiler versions 6.00 and 6.00b (buglist6.00,
buglist6.00b); and in Microsoft BASIC Professional Development System
(PDS) versions 7.00 and 7.10 (buglist7.00, buglist7.10). We are
researching this problem and will post new information here as it
becomes available.
