IPO stands for input process and output!!!! an example of an IPO is a toilet! your input is when you pee or poo in, your process is when you flush the toilet and your output is a clean toilet with probable none of yours or other people's pee and poo in it!!!
isla is the name of the character im using you might see her when im doing information programs in scratch because she will nearly always be the introducer. if its not isla than it will probably be kassie. i have not shown kassie yet but i will when i dont want to use isla! I hope you understand what IPO means now! :D!!! bye!!! ;D
