Csh question

[David Ellis]

In the csh, the expression $name or ${name} looks up the variable with the
given name and substitutes its value.

Is there any way to get the value of a variable whose name is the value of
another variable?

e.g. if we've done set x=a and set a=3, is there any simple csh expression
in terms of x that yields the value of a (3)?

Csh gives an error message "Variable syntax." if I try something like
	echo ${$x}
or even
	echo "`echo {\$}$x`"
