Library /sys$common/syshlp/dbg$help.hlb DEBUG, Messages, CNTRLWRDNOTACCESS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 the vector control word is not accessible

    Facility: DEBUG, VMS Debugger

    Explanation: The debugger does not have direct access to the
    vector control word. Therefore the operands of this instruction
    cannot be displayed correctly.

    User Action: Do not attempt to display the operands of vector
    instructions whose control word is not accessible to the
    debugger.
