Folks, I whipped a couple of wikipedia article about VM subjects a few month ago.
Nothing fancy really, but I realize it'd probably be nice if those get reviewed and possibly checked for accuracy, corrected if necessary, etc..
The 2 articles are : http://en.wikipedia.org/wiki/Group_Control_System%28VM%29#Group_Control_System and http://en.wikipedia.org/wiki/IUCV --Ivan
