* @fileoverview
* Registers a language handler for MUMPS.
*
*
* To use, include prettify.js and this file in your HTML page.
* Then put your code in an HTML tag like
* <pre class="prettyprint lang-mumps">(my SQL code)</pre>
*
* Commands, intrinsic functions and variables taken from ISO/IEC 11756:1999(E)
*
* @author chris.harris@kitware.com
*
* Known issues:
*
* - Currently can't distinguish between keywords and local or global variables having the same name
* for exampe SET IF="IF?"
* - m file are already used for MatLab hence using mumps.
