Instead of writing three-line csh scripts of the form
	#! /bin/csh
	unsetenv TERMCAP
	set term = foo
you could use something like
	alias foo "unsetenv TERMCAP; set term = foo"
Yet, even better:
	alias term "unsetenv TERMCAP; set term = \!* ; tset"
which will work for
	term vt100
	term tvi950
	term h19
	term foo
	term bar
(you can guess how it continues). In fact, you can use any terminal
type in /etc/termcap (Great, isn't it?).

Aliases work much better because they are executed in the current 
environment, whereas scripts are run in a new shell. ...and there is
no way to change the parent's environment just bu calling a script.
