  Syntax:  flagType BadArg( void );
 
  Returns: Always returns FALSE.
 
  See:     ◄Command Table►
 
     BadArg generates an error message stating that the user argument is
     invalid. This function is rarely used because PWB looks at the
     function type as declared in the command table and rejects commands
     with incompatible argument types before the extension function is
     called.
 
     You can use BadArg to signal a failed test for valid input that the
     function performs beyond the tests that PWB automatically performs
     for the argument type. For example, you can use BadArg to exclude
     numeric arguments that are out of range.
