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

     /DEBUG[=(option[,...])]
     /DEBUG=(TRACEBACK,NOINLINE,NOSYMBOLS) (D)
     /NODEBUG

  Includes information in the object module for use by the OpenVMS
  Debugger.  You can select the following options:

  ALL            Includes all possible debugging information.

                 On Alpha systems, /DEBUG=ALL is equivalent to
                 /DEBUG=(TRACEBACK,SYMBOLS).

                 On VAX systems, /DEBUG=ALL is equivalent to
                 /DEBUG=(TRACEBACK,SYMBOLS,INLINE).

  INLINE         Causes a STEP command to STEP/INTO an inlined
                 function call.

  NOINLINE       Causes a STEP command to STEP/OVER an inlined
                 function call.

  NONE           Excludes any debugging information.

  NOSYMBOLS      Suppresses generation of symbol table records.

  SYMBOLS        Generates symbol table records.

  NOTRACEBACK    Suppresses generation of traceback records.

  TRACEBACK      Generates traceback records.

  Specifying /DEBUG with no options is equivalent to specifying
  /DEBUG=ALL.

  If the /DEBUG qualifier is not specified, the default is
  /DEBUG=(TRACEBACK,NOINLINE,NOSYMBOLS).
