Each instruction has its own line. I've indented some for clarity. Instructions are formatted like this: [symbol][number] 1 [param1] 2 [param2] ... > [next] Numbers and text are formatted like this: [symbol]{[literal] > [next]} Example: w1 1 C1 2 n{1 > *} > w2 means:

• Write instruction ID 1
• Parameter 1: C instruction ID 2
• Parameter 2: number with a value of 1 and halting immidiately
• Next instruction: write instruction ID 2 An asterisk as the next instruction means "halt"
