title: How can I define my own commands in MIPS?
body: <p>I need to define 4 own commands. Each of the command is recognisable by first two bits. Then I need to input these commands from .bin file. (something like turtle in LOGO language). What am I supposed to do?</p>
  
  <p>I tried using
  command: .word 0 0
  to generate required words for these commands, but I don't know how to access it now.</p>
