A line of code looks like this: 
       LLLL: OP MMMM
where LLLL is an optional label with a maximum of four characters, OP is an operator chosen from the list and MMMM may be a label, a number or empty depending on the operator. Here's a simple example which adds one hundred to whatever is typed in: 
     LOOP: INP N1
      LDA N1
      ADD #100
      STA N2
      OUT N2
      JMP LOOP
