Error Shell script foreach help

I am writing a shell script to uncompress files in a directory, then call a Perl script to search the files for given terms, store those terms in a different output file , and compress the output. I get a syntax error with my use of foreach. Below is my script.
Code:
#!/bin/csh -fxv

if (! $#argv==1); then
    echo "[fail, not enough input arguments]"
    exit 10
else
    echo "the pitch and kinf will be stored in a new file called" $1
    echo " "
endif
rm $1

# uncompress output files in directory
set list= `/bin/ls *.out.gz`
foreach f ($list)
    gunzip $f
end

#run the pearl script on each output file and compress that file
set list= `/bin/ls *.out`
foreach i ($list)
    ./readfile.pl $i $1
    gzip $i
end

exit 0

# The shell expands meta-characters, so try this:
Code:
foreach f ( *.out.gz )
  gunzip $f
end

Try replacing
Code:
set list= `/bin/ls *.out`

with
Code:
set list=(`/bin/ls *.out`)
