3.2.1.1 -ac
-ac omits false conditionals from a listing. Any lines
that are not assembled because of a false .if or
.ifdef (or the .else of a true
.if or .ifdef) will be omitted from the listing.
The first example shows a listing where the -ac option was not used.
The second example shows a listing for the same source where the -ac
option was used.
Note: Some lines have been omitted, due to the -ac option;
i.e., lines 3-8, 14, 21, 24, 29 and 31.
