/sys$common/syshlp/helplib.hlb DUMP, Qualifiers, /RECORDS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /RECORDS[=(option[,...])]

    Dumps the file a record at a time rather than a block at a time.
    (By default, input is dumped one block at a time for all devices
    except network devices.)

    Records are numbered beginning with 1.

    Select a range of records to be dumped by specifying one of the
    following options:

    START:n    Specifies the number of the first record to be dumped;
               the default is the first record.

    END:n      Specifies the number of the last record to be dumped;
               the default is the last record of the file.

    COUNT:n    Specifies the number of records to be dumped. The COUNT
               option provides an alternative to the END option; you
               cannot specify both.

    If you specify only one option, you can omit the parentheses.

    If you specify the /RECORDS qualifier, you cannot specify the
    /ALLOCATED or the /BLOCKS qualifier.
