Hello Ernie,

As my setup is only a single user host I placed both of these commands
in /etc/csh.cshrc and then disabled .cshrc in both /root and ~/.
Thus, there is only one configuration file for both root and my home
directory.  Have used this setup for many years without incident.

I am using r10.3 amd64.

Cheers ...

Marek
