	echo -n "continue? "
	set foo=$<

Salient points:
The -n leaves the cursor on the same line as the prompt; the
quotes allow a space after the prompt; $< reads the script's
standard input up to a newline; and, foo will contain everything
typed, including whitespace, but not the newline.

RTFM for csh(1) and echo(1).  You could have learned all of
this there.  It's the advice of everyone who's ever
answered (or asked) a question on the net that you exhaust
your resources before asking such questions.

The standard way is to use the pseudo-variable "$<" as follows--

	#!/bin/csh
	echo -n "Really [yn]? "
	set answer = "$<"
	echo "You answered '$answer'"

Well, yes, it's convoluted.  But you don't have to write a new
tool to do it this way--

	#!/bin/csh
	echo -n "Really [yn]? "
	set answer = "`head -1`"
	echo "You answered '$answer'"

I have found that
	echo "say what?" | tr -d '\012'
is the most portable way to handle both
	echo -n
and	echo stuff\c

The ancient csh's supplied as value-added by most System V vendors do not have
$< --- the manual csh(1) won't help here.  But there is usually a "line"
command that can be used similarly:

	echo "continue? \c"
	set foo="`line`"
