Expressed as: Opr Arg1, Store/result

No arg2

Use # for numbers

If there is a while or if, add jmpf right away only

do while uses jmpt only

jmpf always come first

ex: a = a * a

mov a, R0

mul a, R0

mov R0, a

1. mov #0, a (int a = 0)
2. mov #0 i (i = 0)
3. move i, R0 (prep for operation, beginning of for loop) [R0 = i = 0]
4. lt #10, R0 (i < 10) [R0 = R0 < 10 = T/F]
5. jmpf R0, [17] (for loop condition is fale)
6. mov i, R0 (prep for operation, beginning of if statement) [R0 = i]
7. mod #2, R0 (i % 2) [R0 = R0 % 2]
8. eq #0, R0 (... == 0) [R0 = R0 == 0 = T/F]
9. jmpf R0, [13] if condition is false, go to increment in loop
10. mov a, R0 (prep for operation) [R0 = a]
11. add i, R0 (a + i) [R0 = a + i]
12. mov R0, a (a = a + i)
