VA Kernel 186512 29335493 2005-11-27T01:19:49Z Cmdrjameson 101935 spelling 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 [[Category:Operating systems]]
