The full command-line option is /[NO]LIST[=file-spec]. Controls whether a listing is created and optionally provides an output file specification for the listing file. Do not use wildcard characters in this file specification. If you enter the MACRO/ALPHA command interactively, the default qualifier is /NOLIST. The assembler sends output to the current output device rather than to a listing file. If you execute the MACRO/ALPHA command in a batch job, the default qualifier is /LIST. If you do not specify a file specification, the assembler creates a listing file using the same name as the source file. For example, if you use a source file named XXX.M64, the assembler creates a listing file named XXX.LIS.
