/MACHINE_CODE D=/NOMACHINE_CODE

 /[NO]MACHINE_CODE

 Controls whether the listing file includes a symbolic
 representation of the OpenVMS Alpha object code generated by the
 compiler.  Generated code and data are represented in a form
 similar to a MACRO assembly code listing.  The code produced by the
 /MACHINE_CODE qualifier is for informational purposes only.  It is
 not intended to be assembled and is not supported by the MACRO
 assembler.

 If a listing file is not being generated, the /MACHINE_CODE
 qualifier is ignored.

 The default is /NOMACHINE_CODE.

 See the HP Fortran for OpenVMS User Manual for a description of
 the format of a machine code listing.
