It works under Ultrix 1.2.

I'm not positive, but I *think* that I had some problem with programs run from
the script not inheriting the set-uid priviledges, ie, I once had something 
like:

   file "test":
      #!/bin/csh
      a.out
      other commands....


Assume "test" was owned by "root" and had set-uid bits on, and "a.out"
was owned by something other than root.

then, running "test" did not run "a.out" with root's priviledges.

I won't swear to this though, since at the time I ran into the problem
I found some other way to deal with things and never really did 
look into the matter thoroughly.  (sorry).
