Hi.

Sorry, dont know the trick for csh -- but for bash there is an env, 
which can be used to override word-split whitespaces:
IFS  (see bash(1))

The following script should do the trick (i have tested it with some 
filenames with spaces in it succesfully):
8<----8<----8<----
#!/bin/sh
IFS="
"
export IFS;
for i in *;
 do
         mv $i `basename $i .par2`.PAR2;
         echo $i;
done;
8<----8<----8<----8<

note how IFS is set to newline

(replace the *-wildchar in the for-line with your fileset)

Hope it helps
greetings,
