5.6.3 Nolist Directive
The .nolist directive controls (in conjunction with
            .list) whether assembly listings are generated. This
         directive decrements an internal counter (which is one initially). Assembly listings are
         generated if this counter is greater than zero.
This directive is only functional when listings are enabled with the
            -a command line option and forms processing has not
         been disabled with the -an command line option.
