Record Management Services

Record Management Services (abbreviated RMS) are procedures in the VMS, RSTS/E, RT-11 and high-end RSX-11 operating systems that programs may call to process files and records within files. VMS RMS is an integral part of the system software; its procedures run in executive mode. (RMS was not integrated into RT-11 and RSTS/E, but was available as a "layered product".)

RMS supports four record access methods:

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