OpenVMS Record Management Services (RMS) are generalized routines
    that assist user programs in processing and managing files and
    records. RMS provides transparent network processing between
    DECnet for OpenVMS nodes. RMS also includes a set of macro
    instructions that you can use to initialize control blocks,
    store values in control blocks, and call RMS services. For
    more information about RMS, see the OpenVMS Record Management
    Services Reference Manual and the FDL Facility in the OpenVMS
    Record Management Utilities Reference Manual.
