RMS supports four record access methods:

• Sequential Access
• Relative Record Number Access
• Record File Address Access

RMS supports four record formats:

• Fixed length
• Variable length
• Variable record length with fixed-length control blocks
• Stream files (records separated by termination characters)
  • STREAM: Records terminated by CRLF
  • STREAM_CR: Records terminated by CR
  • STREAM_LF: Records terminated by LF

Digital provided the File Definition Language (FDL) which could be used to define the structure of an RMS file.
