RMS

   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.
