WARNING!  Microsoft's QuickBASIC compiler version 3.0 has a BUG in it
that affects ADVBAS users!  If you compile a program using ADVBAS in the
programming environment with the compile-to-BCOM30 option, the results
will be unreliable at best.  If you need to generate stand-alone programs,
do not use the programming environment with compile-to-BCOM30.  Instead,
compile from the command line.  Check your QuickBASIC manual for more
information if you are unfamiliar with that method.  A typical syntax will
be:

   QB filename/O;

with a letter "O", not the number zero.  You may need additional switches
besides the "/O", depending on your program.
