Help with a couple commands

[46and2]

Hello, I have been going over the commands list as of late, and have passed over a few things multiple times that I honestly couldn't figure out what to do with. I don't understand Tokenize and arrays are a mystery to me. I understand that arrays can hold multiple numeric data, but I don't know how to access them properly. Looking over the board I have seen tokenize used before, but I don't see how it holds the variables(Words instead maybe?). I am sorry to sound like a beginner, but I am lost and was hoping if some of you could help me. Any explanations on what these commands do, what they are used for, and how they are used would be greatly appreciated. Thanks for your time.
