1 ============
1 
1 Control (in conjunction with the '.nolist' directive) whether or not
1 assembly listings are generated.  These two directives maintain an
1 internal counter (which is zero initially).  '.list' increments the
1 counter, and '.nolist' decrements it.  Assembly listings are generated
1 whenever the counter is greater than zero.

1    By default, listings are disabled.  When you enable them (with the
1 '-a' command line option; ⇒Command-Line Options Invoking.), the
1 initial value of the listing counter is one.
