LIST (Listing Control)
The LIST and NOLIST directives control whether assembly source statements
are included in a listing file (produced by specifying the --listing keyword on the
command line; see Output Files). The LIST directive instructs the assembler to
include all subsequent source statements in the listing file until it encounters a
NOLIST directive. Unless you specify NOLIST, the assembler assumes LIST
by default. The LIST directive itself is shown in the listing file.
See also NOLIST (Listing Control), PAGE (Listing Control), and SUBHEAD
(Listing Control).
Syntax:
The LIST directive has no arguments and cannot have a label.
