/sys$common/syshlp/helplib.hlb BASIC, /MACHINE_CODE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   The /MACHINE_CODE qualifier controls whether the listing file  contains  a
   list of compiler generated machine code.

   The format of the /MACHINE_CODE qualifier is as follows:

      /[NO]MACHINE_CODE

   The /NOMACHINE_CODE qualifier suppresses compiler generated  machine  code
   in the listing file.

   The default is /NOMACHINE_CODE.
