The ,0 is a null character. It tells the _puts command to stop reading text at
that point. If it wasn't there, you'd get your string and a bunch of garbage,
and it would keep reading until it found a byte of zeroes somewhere in the
memory. The string is stored in binary as ASCII data, then ends with a byte of
zeroes. _puts (or any other display call) stops when it reaches that point.
