Can someone walk me through the following problem step by step?

The code below uses the Space macro which simply displays the number of blank spaces specified by its argument. What output is generated by this MASM "program"?

I know that the answer is: 6 _ _ 5 _ _ 4 _ _ 3 _ _

But I don't get how we get there.

main PROC 8 push 3 push 7 call rcrsrn exit main ENDP rcrsn PROC push ebp mov ebp, esp mov eax, [ebp 12] mov ebx, [ebp+1 cmp eax , ebx j1 jmp quit 8 recurse recurse: inc eax push eax push ebx call rcrsrn mov eax, [ebp 12] call WriteDec Space 2 quit: pop ebp ret 8 rcrsn ENDP
