The MUMPS (M) programming language has long been used in health-care. Its history and other details can be found here. Version 2.0 of a compiler to translate Mumps (M) to C is now available. Translations such as this make it easy for programs written in MUMPS to run on any computer. It implements
a substantial sub-set of the 1995 Mumps (M)
standard. This compiler includes support for limited indirection (“@” level
only at present), B-Tree based global arrays,
SQL (PostgreSQL) and extensions. In addition, it has code to facilitate development of web server-side applications. Details, download and documentation can be found here.
