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

    If your program has multiple symbols with the same name, you
    may need to use path names to resolve symbol ambiguities. For
    example, your program may have a variable X in procedure A,
    another variable X in procedure B which is nested in procedure
    A, and still another variable X in procedure C. If you specify X,
    as in this example, the debugger uses symbol search conventions
    (based on the PC scope) to resolve the ambiguity:

    DBG> EXAMINE X

    If the debugger cannot do so, it issues the following message:

    %DEBUG-W-NOUNIQUE, X is not unique.

    To resolve the ambiguity, you can specify which X you want by
    using a path name. For example:

    DBG> EXAMINE A\X
    DBG> EXAMINE A\B\X
    DBG> EXAMINE C\X
