> Variables have to go somewhere. Good luck finding them amidst all the confusing rolling, picking, duping, etc. Of course you don't want to use roll or pick. That's tutorial-level knowledge that you shouldn't use them. What you do when you see that coming is that you offload something to a global variable. The "something" is often the central topic of some part of the program, like a file handle for instance. So it makes sense to put it in a variable because it's needed in many places.
