|I am with LMiller7. What do you mean by notepad? I doubt if you mean the Window's appliction by the same name?|
Most of the modern programming languages can reserve memory for it's own use. For example, a "C" program can reserve memory (using malloc) and write to it and read from it as desired.
Back in my day, we didn't refer to it as a 'notepad'. We called it a 'scratch pad' or a 'buffer'.
