 +Lets look at what is happening here, so we have created an array called primeAr and we have a loop that starts at 2 and goes till upperBound which could be 1024, 2048, and so on. Inside the loop, we are specifying the index at a given point in the array and assigning it pop. This is populating our array going 2,3,4,5,...upperBound which will be important for the logic later down the line.
 +
 +Now lets look at that in asm:
 +<code asm>
 +    mov R8, primeAr ; Starting point goes into R8
 +    iadd R8, 2      ; Incrementing R8 by 2
 +    mov R9, 2       ; starting point/number (pop in C)
 +
 +_bLoop:
 +    ; Loop condition
 +    mov R13, R9
 +    ile R13, R2
 +    jf R13, _bLoopEnd
 +
 +    mov [R8], R9 ; R9 moved into R8 array at current index
 +    iadd R8, 1   ; Increment memory address
 +    iadd R9, 1   ; Increment loop
 +
 +    jmp _bLoop ; Back to start of loop
 +
 +_bLoopEnd:
 +</code>
 +
 +As you can see the logic is very similar but just knowing how to write it might be the hard part but after doing a couple look overs and experimenting it will click.
