This option allows the user to control whether or not listing information is generated on a specific pass of the assembler. By default, the assembler only generates listing information on pass two. If the user is encountering "phase errors" or other unusual situations, it may be helpful to request a listing for the first pass as well.
The arguments to this option are either a series of numeric digits (without intervening white space) or the ALL or NONE keywords. In the default assembler configuration, use of the -Lp:ALL form is equivalent to specifying -Lp:12, because the assembler makes two passes through the source file by default. The NONE keyword prevents generation of any pass-related information in the listing file; however, symbol table information will still appear if selected.
When using numeric digits to specify the desired pass numbers, a listing will only be generated for the numbers given in the argument field; the default setting (or settings given by previous occurrences of the option) will be discarded.
