How do you break down a string?

Ok, i was hoping to create a basic code for my RPG that will store the players: name, experience, item, and gold but i don't know how to set each letter in the players name to a varible. Anyone know how to? or do i have to use jass?

(if you can supply me with a code similiar to this that doesn't require all that extra editor stuff then that will be great too).

Anyone? You can just give me the trigger functions that do it if you can.
