008D9402 <...> is not a valid editor within DEC DATATRIEVE.

    Explanation:

    You have assigned the logical name DTR$EDIT to an editor not
    currently supported by DEC DATATRIEVE.

    User Action:

    Redefine the logical name DTR$EDIT.

    From within DEC DATATRIEVE, use the FN$CREATE_LOG function to
    redefine the logical name.

    At the DCL level, use the DEFINE or ASSIGN command to redefine
    the logical name. Do not use the FN$SPAWN function (creating a
    subprocess) to get to the DCL level in this instance. Commands
    issued from the subprocess will not take effect in the original
    process.
