/DEBUG

    /DEBUG[=(option[,...])]
    /DEBUG=(TRACEBACK,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).

 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,NOSYMBOLS).
