How do I use arrays?

Could anyone point me towards a good tutorial?

I need it for my game’s inventory system

How would I got about making a text based inventory system? What I mean by that is instead of having pics for each type of item it has just a line of text with item name. The only way I can think is make a large box and make bunch of movieclips where the first frame is empty and then if they obtain that item it goes to the 2nd frame where the text is and a dynamic txt box with the number of that item. Is there an easier way to this? And yes these items will be used for things so they need to be able to be refrenced to.

Would this be able to be done in an array? If so how? I have no idea how to work with arrays. Just so there is something to work with here is some items with Id’s

Items - Item ID
Iron ore---------1
Copper ore------2
Wooden stick----3
Rock------------4
