The ''VA Kernel'' is a set of programs, developed by the Department of Veterans Affairs of the United States Government, which provide an operating system and [[MUMPS]] implementation independent abstraction to the [[VistA]] Hospital Information System. These programs (called 'routines' in MUMPS) are the only programs which are expected to not be written in ANSI Standard MUMPS.
The [[CHCS]] system and the [[RPMS]] system have a Kernel as well, which provides a similar degree of support to those systems as the VA Kernel does to [[VistA]].
The VA Kernel provides abstractions for:
* Menu Management (MenuMan)
* Login and Access Security
* Task scheduling and Batch processing
* Input/Output devices
* Protocol and Event processing
* Date processing and manipulation
* Mathematical and common library functions
