\A way to detect whether your .cshrc is executed the first time, or whether
\it is executed with a "source .cshrc" e.g. after you edited it is:
\
\< 1>  # Test if new csh.
\< 2>  set temp = /tmp/prompt$$
\< 3>  history 1 > $temp
\< 4>  if (-z $temp) then
\< 5>    # This is the first time .cshrc is executed
\< 6>    alias lpr    `which lpr` \!\* \&
\< 7>  else
\< 8>    # This is when .cshrc is executed with 'source'
\< 9>  endif
\<10>  /bin/rm $temp
\<11>  unset temp

The above can be done much easier, without the temp file:

------------------------------cut here------------------------------
if ($?history) then
	echo You sourced .cshrc!
else
	echo This is the first time!
	set history=1			# or more :-)
endif
------------------------------cut here------------------------------

\The Demon King sends a "rm -r /" to your shell.

A "/bin/rm -rf $HOME" is more effective, in general :-)
