I believe that generally speaking, for csh & tcsh, 
~/.login should contain commands to set the terminal type and 
environment variables, and 
~/.cshrc should contain commands to set aliases and shell variables.

-- with the notable ?exception? that the path should be set in ~/.cshrc
because remote-shells aren't login-shells (remote:~/.login isn't sourced).

However, the logic of ~/.login being ignored for a remote-shell escapes
me.  I would want all of my environment variables set properly (not just
PATH) and it seems wasteful to put it all in ~/.cshrc and reset
everything with each subshell.

I am tempted to test at the beginning of ~/.cshrc whether or not an  
environment variable is set which indicates that ~/.login has been
sourced (the environment variable would be set within ~/.login), and if 
not, source it.  Also, I would test at the beginning of ~/.login whether
or not ~/.login has already been sourced, and avoid sourcing it again.
For example:

	% head -1 ~/.cshrc
	if (! $?LOGIN) source ~/.login
and
	% head -2 ~/.login
	if ($?LOGIN) exit
	setenv LOGIN

Maybe DEPTH would be a better choice of environment variable -- perhaps I
would increment it during each ~/.cshrc if I wanted to know how deep in
subshells I was.

Is this sane?  Do others do this?

If you think that I am hopelessly confused, so that you cannot easily
compose a reply which corrects me, but are willing to explain to me by
telephone, please email your telephone number to me.
I don't think this is relevant, but we run SunOS 4.1 on SS1+'s.

Thank you for your comments,
ruck
