008D8AD2 Can't ERASE from a sequential file (domain <domain-
    name>).

    Explanation:

    You cannot erase a record from a sequential file.

    User Action:

    Either leave the file as it is, or define a new indexed file from
    which you can erase records. To define an indexed file, use the
    DEFINE FILE command, specifying a key field. Then transfer the
    data with a Restructure statement.
