is a high level interactive computer programming language for use in complex data handling operations. It has extensive string handling capabilities and a hierarchical database structure that efficiently handles sparse and variable-length data, making it especially suitable for databases with vast amounts of free text. M has unique features including the ability to store both data and program statements in its database, a fundamental property of object-oriented programming. In addition, formulas written in a program can be permanently stored and used by other programs. Developed in l966 at Massachusetts General Hospital as MUMPS, it has been used extensively in the healthcare field. The MUMPS Development Committee has accepted responsibility for creation and maintenance of the language since early 1973. The first ANSI approved standard was approved on 15 September 1977 via the canvass method.

The following M example converts fahrenheit to centigrade:

READ "Enter fahrenheit ",FAHR
SET CENT=(FAHR-32)*5/9
WRITE "Centigrade is ",CENT

This can also be written as:

R "Enter fahrenheit ",FAHR S CENT=(FAHR-32)*5/9 W "Centigrade is ",CENT
or

R "Enter fahrenheit :,FAHR W "Centigrade is ",(FAHR-32)*5/9
