csh filename substitution

[lawesn at SouthBank.UUCP]

Apologies if this question has popped up in the past but...

I was trying to rename a group of files from 'st.*' to '*'

e.g.
	st.fred.dat	=>	fred.dat
	st.jim.c	=>	jim.c
	st.nick		=>	nick

I noticed that there was (according to the csh manual) an operator :s/l/r/
which was supposed to substitute 'r' for 'l' within the filename.

So, I tried (amongst other things):

	foreach i (st.*)
	mv $i $i:s/st.//
	end

This replies with a message 'Variable syntax'

Could some kind soul out there please point out to me what I am doing wrong.
I could achieve the correct result with sed, but would like to use this
apparently nice feature (bug :-) in csh.

Thanks.
