setting REMOTEHOST on rlogins

[karl anderson]

I'm just getting acquainted with SGI machines after using Suns alot.
I see that when I rlogin to one of our Irises, an environment variable
named "REMOTEHOST" is set to the name of the machine I'm logging in
from.  Is this something unique to IRIX?  I'd love to be able to do 
that on my Suns - can anyone tell me how?  Please answer by email,
as I don't ordinarily take this group.  TIA.
