You can use the eval command:

$ showargs() {
        for i in $(seq $#); do
                eval FILE=\$$i
                echo $FILE
        done    
}
$ show_args one two three
one
two
three

or you can use the shift built-in command:

$ show_args() {
        while : ; do
                FILE=$1
                echo $FILE
                shift || break
        done
}

Although this takes an extra round which finds $1 unset in the last
loop. The details are left as an exercise :-)
