0.1.5 Precedence of Command-Line Options and Listing Directives

Since command-line options and source code directives can specify opposite behavior for the same listing file option, the assembler interprets the commands according to the precedence levels below. Selecting PWB options is equivalent to specifying /Fl /Sletter on the command line:

/Sa overrides any source code directives that suppress listing.

Source code directives override all command-line options except /Sa.

.NOLIST overrides other listing directives such as .NOLISTIF and .LISTMACROALL.

The /Sx, /Ss, /Sp, and /Sl options set initial values for their respective features. Directives in the source file override these command-line options.
