7.55 '.list'
============
Control (in conjunction with the '.nolist' directive) whether or not
assembly listings are generated. These two directives maintain an
internal counter (which is zero initially). '.list' increments the
counter, and '.nolist' decrements it. Assembly listings are generated
whenever the counter is greater than zero.
By default, listings are disabled. When you enable them (with the
'-a' command-line option; 
Command-Line Options Invoking.), the
initial value of the listing counter is one.
