Today:
	Let's print numbers!
	Maybe we could get numbers from the user too!

A Print Number function:
	write requires a memory location
		NOT a register with a value in it
		Actually makes it kind of a pain to call
	So what we need to do:
		Convert our number to ASCII and put it in memory
		Call write on that memory
	We'll allocate memory on the stack
		Subtract from the stack pointer
	Convert to ASCII in a loop
		Figure out the digit, add 48
	Why call write just once
	Think about clobbering registers

If we have time:
	How about reading in a number?
	read, into a buffer
	Convert from ASCII into an actual number

Active Learning:
	Something involving using one or the other
	Maybe a loop that counts up until you use ctrl+c?

Next time:
	project 2
	files
	records (we'll save and restore something or other)
