How to print number before argument?

Hey everyone,

I need to write a script that will display the number of the argument before displaying the argument itself. Here's what I have so far:

for arg in "$@"
do
echo $#:$arg
done

This returns the sum of all arguments preceding the arguments themselves.

$(script) a b c
3:a
3:b
3:c

But I want...

$(script) a b c
1:a
2:b
3:c

Thanks

One way:
Code:
$ cat nargs
#! /bin/ksh

i=0
while ((i<$#)) ; do
        ((i=i+1))
        eval arg=\$$i
        echo ${i}:${arg}
done
exit 0
$ ./nargs a b c d
1:a
2:b
3:c
4:d
$
