Help with a couple commands

[46and2]

Alright, so an array holds the different sets of numeric data, and you can call one part of the set by it's index. Would it be possible then, to show an image or put an explosion at 4 points in a level with a single command? Or would you still need to call each number in the array individually? That helped alot to give me an idea of what an array is and how it's information can be retrieved, thanks. Any suggestions on what I could try to script to see if I understand how to use an array? Sorry for all the questions, I am just happy to start learning about some of this stuff.
