Iteration Help

[Brian E. Seppanen]

I want to define the following

users = ( "user1 user2 user3 user4" )

I then want to call it.

shellcommands:
        any::
                "/usr/local/bin/add_user.pl $users"


What I want the script to do is pass a single username.    In the script I 
would use getent to determine if the user account exists and if not then 
add the account.

Will iteration work so that it does only pass a single user each time? 
Wanted to make sure.

Thanks,
