Are you sure that address is right?  seems a little short and it doesn't work
when I try it.  This tar.z thing is a real pain, I have unzip and VMStar which
I hope will work.  Though I still haven't figured out to run them using run
with parameters.  The VAX is about as userfriendly as a wet paper bag full of
wet paper bags.  Thanks for you help, it is much appreciated.
By the way, if anyone is really bored this Friday night and is looking for
something to do, they could always do my whole assignment, that would be much
appreciated also.  Gee I hope Paul doesn't read this one too!
