If you do

	foreach i ("`cat file`")
	#misc processing
	end

you will get the whole line.  However, when I tried this just now, I
realised that if there are any wild cards (?,*,[,]) then it gives the
strange error message 

	end: No match

when it gets to the line containing the ? or whatever.  Can anyone
explan this one?

I suppose when csh interprets the output of the `...` , it ignores the
quotes, but I have no idea why it should do so!!

Way back in my first year (and most of the second) I was there slaving
away at sorting out which quotes to use in csh/sh and when or not to
use a backslash etc, and I got so fed up, that I haven't written any
scripts since (except for the simplest type) and now everything is in C.  
OK, it takes a lot longer to write, but it's a lot faster, it's more
reliable, and a lot more powerful!
