how do I create a program using parameters using ti-basic 83

I am trying to create a simple program on my ti-84 plus that uses parameters when being called, like a function, but I have had no luck at finding documentation on the internet.

I am wanting to call the program like: Simpleprogram(xyz,X), or something like that

In 83/84 Basic? It is impossible, the best you can do is prompt the user for input or load the parameters into a list on the screen, press enter to load into Ans, and work with the data out of a list.
