       /DEBUG[=option]
       /NODEBUG (default)

    Includes or excludes local symbols in the symbol table or
    traceback information in the object module. You can replace the
    /ENABLE and /DISABLE qualifiers with the /DEBUG and /NODEBUG
    qualifiers when you use the appropriate DEBUG and TRACEBACK
    options. The /DEBUG or the /NODEBUG qualifier overrides debugging
    characteristics set with the .ENABLE or .DISABLE assembler
    directives.

    You can specify one or more of the following options:

    ALL         Includes in the object module all local symbols
                in the symbol table, and provides all traceback
                information for the debugger. This option is
                equivalent to /ENABLE=(DEBUG,TRACEBACK).
    NONE        Makes local symbols and traceback information in
                the object module unavailable to the debugger. This
                option is equivalent to /DISABLE=(DEBUG,TRACEBACK).
    SYMBOLS     Makes all local symbols in the object module
                available to the debugger. Makes traceback
                information unavailable to the debugger. This option
                is equivalent to /ENABLE=DEBUG and /DISABLE=TRACEBACK
                together.
    TRACEBACK   Makes traceback information in the object module
                available to the debugger and local symbols
                unavailable to the debugger. This option is
                equivalent to /ENABLE=TRACEBACK and /DISABLE=DEBUG
                together.

    If you specify no options to the /DEBUG qualifier, it assumes the
    default value of /DEBUG=ALL.
