If you really want to do each line then I guess the way would be ...

IF array1 bit1 = array2 bit1 then
IF array1 bit2 = array2 bit2 then
IF array1 bit3 = array2 bit3 then
......on and on and on....

But something like Charles said
IF check1 = check2 then
IF check2 = check3 then
IF check3 = check4 then
Hey. it is done...
