Specify the --list= assembler option to turn
on listing.
By default the --list= option produces a
normal listing that includes variable declarations, macro expansions,
call-conditioned directives, and MEND directives. The
listing is produced on the second pass only. Use the OPT directive
to modify the default listing options from within your code.
You can use OPT to format code listings. For
example, you can specify a new page before functions and sections.
