VMS Help EXAMINE, Parameter  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 location[:location]

    Specifies a virtual address or a range of virtual addresses
    (where the second address is larger than the first) whose
    contents you want to examine. If you specify a range of
    addresses, separate the beginning and ending addresses with a
    colon (:).

    A location can be any valid arithmetic expression containing
    arithmetic or logical operators or previously assigned symbols.
    Radix qualifiers determine the radix in which the address is
    interpreted; hexadecimal is the initial default radix. Symbol
    names are always interpreted in the radix in which they were
    defined. The radix operators %X, %D, or %O can precede the
    location. A hexadecimal value must begin with a number (or be
    preceded by %X).

    The DEPOSIT and EXAMINE commands maintain a pointer to the
    current memory location. The EXAMINE command sets this pointer
    to the last location examined when you specify an EXAMINE
    command. You can refer to this location using the period (.)
    in a subsequent EXAMINE command or DEPOSIT command.
