You can move through an argument list using the shift command. Here's an example using an inline while loop and and an inline for loop.
# sh
The while loop
# set M Y S Y S A D B L O G
# while [ $# -gt 0 ]
> do
> echo $*
> shift
> done
M Y S Y S A D B L O G
Y S Y S A D B L O G
S Y S A D B L O G
Y S A D B L O G
S A D B L O G
A D B L O G
D B L O G
B L O G
L O G
O G
G
The for loop
# set M Y S Y S A D B L O G
# for i in $*
> do
> echo $*
> shift
> done
M Y S Y S A D B L O G
Y S Y S A D B L O G
S Y S A D B L O G
Y S A D B L O G
S A D B L O G
A D B L O G
D B L O G
B L O G
