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

 breakpoint or tracepoint being set in a different module.

    Facility: DEBUG, VMS Debugger

    Explanation: The specified line number was not found in the
    current module. Consequently, Debug is setting the breakpoint
    or tracepoint in a module later in the call stack or in a set
    module not on the call stack.

    User Action: If the breakpoint or tracepoint was intended to be
    set in the current module, cancel the breakpoint or tracepoint
    and specify a line number in the current module.
