- M/VAXDSM from Digital Equipment Corporation (DEC) on VAX/VMS
- M/YottaDB YottaDB from YottaDB.com (open source, commercial)
Definition of the Language
Any program written in M (MUMPS) that is stated as being written in Standard M must conform to the ANSI X11.1 or ISO standard for the language.
Any implementation of M (MUMPS) that is to be qualified as Standard M must conform to the same standard.

Factoids about M
- The M ways that can affect the value in a local or global variable are: M/FOR, M/KILL, M/MERGE, M/NEW, M/QUIT, M/READ, M/SET, M/NEW, M/TRESTART, M/TROLLBACK,
- passing as an argument using M/DO or $$ or M/JOB,
- the $INCREMENT function and any non-standard syntax
- any implementation-specific semantics such as M/BREAK, M/CLOSE, M/OPEN, M/USE, M/VIEW, Y* and Z*
- There are other ways SSVNs and Intrinsic variables can be changed not listed here.
