VMS Help MACRO, VAX MACRO Assembler, /DISABLE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /DISABLE=(function[,...])
       /NODISABLE

    Provides initial settings for the functions disabled by the
    .DISABLE 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.

    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
    /DISABLE=(ABSOLUTE,DEBUG, TRUNCATION, VECTOR). The /NODISABLE
    qualifier has the same effect as not specifying the /DISABLE
    qualifier, or negates the effects of any /DISABLE qualifiers
    specified earlier in the command line.
