/DEBUG=TRACEBACK (D)

  Requests that information be included in the object module for  use
  with the OpenVMS Debugger.

  It is strongly recommended that you use the  /NOOPTIMIZE  qualifier
  when   you  use  the  /DEBUG  qualifier.   Optimization  can  cause
  confusing results during a debugging session.

  When /DEBUG is specified, the  compiler  generates  small  routines
  that  are  used  only  by the debugger.  When the program is linked
  with /NODEBUG, these routines will still be included in the program
  but will not be used.  For this reason it is recommended that final
  versions of programs be recompiled  with  /NODEBUG  (which  is  the
  default).

  You can select the following options:

        ALL          Includes symbol table records and traceback
                     records. /DEBUG is equivalent to /DEBUG=ALL.

        SYMBOLS      Includes the symbol definitions for all
                     identifiers in the compilation. This is the
                     default for symbols if the /DEBUG qualifier is
                     used.

        NOSYMBOLS    Does not include symbol definitions. Without
                     symbol definitions, traceback is done
                     according to virtual address.

        TRACEBACK    Includes only traceback records. This is the
                     default if the /DEBUG qualifier is not present
                     on the command.

        NOTRACEBACK  Does not include traceback records.

        INLINE       Generates debug information to cause a STEP
        (OpenVMS     command to STEP/INTO an inlined fuction call.
        VAX only)

        NOINLINE     Generates debug information to cause a STEP
        (OpenVMS     command to STEP/OVER an inlined fuction call.
        VAX only)

        NONE         Does not include any debugging information.
                     Use this option to exclude all debug
                     information from thoroughly debugged
                     program modules. /NODEBUG is equivalent to
                     /DEBUG=NONE.

  If you omit the /DEBUG qualifier, the default is /DEBUG=TRACEBACK.
