/LIST[=file-spec] D=/NOLIST (interactive)

 /NOLIST

 Controls whether the compiler creates a source listing file.  If
 you  omit  the  file specification, the compiler defaults to the
 name of the first source file, your  default  directory,  and  a
 file type of .LIS.

 The compiler does not produce a listing file in interactive mode
 unless  you  specify  the  /LIST  qualifier.  In batch mode, the
 compiler produces a listing file by default.   To  suppress  the
 listing file, use the /NOLIST qualifier.

 In either mode, the listing file is not  automatically  printed.
 You  must use the PRINT command to obtain a line printer copy of
 the listing file.
