Look into using tokenized strings. You can build a list using $addtoken and you get the individual items using $gettoken. For listing them one at a time you can do a while loop and loop through the tokens in your list. If the list is going to get large and don't want to spam a lot of messages at once a timer could be added also.
Take a look at the token commands and see what you can figure out yourself. Post back if you need more help.
