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
