 pathname too long at path_name

    Facility: DEBUG, VMS Debugger

    Explanation: The entered pathname is too long for the debugger to
    handle.

    User Action: Shorten the pathname entered, either by abbreviating
    the pathname, defining a symbol for the pathname, or setting a
    search scope so that you can use a shorter pathname.
