Aren't we all?  :-)

It probably does work fine.  Perhaps finer on itanic than Alpha. 
Understandable.  But I have no compelling reason to do such upgrades, 
I'm lazy, and if it ain't broke, I'm not fixing it.

I've agreed strongly with this concept.

The problem, as I see it, (sorry Philip), is that Philip seems to want 
to explore the boundaries, however, when expertise is called for, he 
claims to not be an expert in the required areas, and he doesn't have 
VMS software support to call upon.

He's probably good at clusters, HBVS, and such.  Better than me who has 
never been exposed to any of that stuff.
