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

 error handle signalled, address = address

    Facility: DEBUG, VMS Debugger

    Explanation: The debugger signalled an error handle. This should
    never happen. The error handles are an internal construct which
    are used to obtain information within the debugger. They should
    never appear in user-visible messages.
