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

       /ENABLE=(function[,...])
       /NOENABLE

    Provides initial settings for the functions controlled by the
    .ENABLE assembler directive. You can specify one or more of the
    following functions:

    ABSOLUTE    Assembles relative addresses as absolute addresses.
    DEBUG       Includes local symbol table information in the object
                file for use with the debugger.
    GLOBAL      Assumes undefined symbols to be external symbols.
    SUPPRESSION Suppresses listing of unreferenced symbols in the
                symbol table.
    TRACEBACK   Provides traceback information to the debugger.
    TRUNCATION  Truncates floating-point numbers (if truncation is
                disabled, numbers are rounded).
    VECTOR      Enables the assembler to accept and correctly process
                vector code.

    The /NOENABLE qualifier has the same effect as not specifying
    the /ENABLE qualifier, or negates the effects of any /ENABLE
    qualifiers specified earlier in the command line. You can
    specify one or more of the functions listed in the description
    of the /DISABLE qualifier. If you specify only one function,
    you can omit the parentheses. If you specify no functions
    in the /DISABLE qualifier, it assumes the default value of
    /ENABLE=(GLOBAL,TRACEBACK,SUPPRESSION).
