008D89BA Invalid string descriptor.

    Explanation:

    The token type your program passes to the callable DEC DATATRIEVE
    routine, DTR$GET_STRING, is not a valid token type.

    User Action:

    Correct your program to use a valid token type. The DEC
    DATATRIEVE Guide to Programming and Customizing lists valid
    token types. If you see this error in interactive DEC DATATRIEVE,
    please submit an SPR, if you are eligible.
