VMS Help RCP, Qualifiers, /PRESERVE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /PRESERVE
       /NOPRESERVE

    Optional.

    Preserves the file protection mode and modification date during a
    copy. The creation date and modification date of the output file
    are set to the modification date of the input file. The dates
    are truncated to the second on transfer. When these dates are
    displayed on OpenVMS, the "hundredths of a second" field will
    always be zero.

    When a file is created by RCP/PRESERVE on an OpenVMS system
    running TCP/IP Services, WRITE permission on the input file
    grants both WRITE and DELETE permission on the output file.
