ARM Dynamic Listing Directive Options

  • Article

The OPT directive is used to set listing options from within the source code, if listing is turned on.

The default setting is to produce a normal listing, including the declaration of variables, macro expansions, call-conditioned directives, and MEND directives, but without producing a listing during the first pass.

These settings can be altered by adding the appropriate values from the list and using them with the OPT directive as shown in the following table.

OPT n Effect
1 Turns on normal listing.
2 Turns off normal listing.
4 Page throw: issues an immediate form feed and starts a new page.
8 Resets the line number counter to 0.
16 Turns on the listing of SET, GBL, and LCL directives.
32 Turns off the listing of SET, GBL, and LCL directives.
