Write a PDP-8 program that clears as much memory as possible, using no more than 100 (base ten) lines of code. If your program clears all memory, including the program itself, you will earn an A+. Clearing all but one location is worth an A, all but two is worth an A-, etc. Note, by the way, that if you clear all memory, your program will not halt by itself. (What will it do?)
