Org 0 tells the assembler the address to assemble to.  It doesn't
generate any code.  It effects jumps and calls, etc.

In this code:

start:  some instruction
	some more instructions
	jp   start

if .org 0 is used at the begining the address in the jp will be 0.
if .org 100 is used the jp will be to 100.

The org statement itself only effects the assembler.  It doesnt
get put in the program.
