May be it's time to make more than 1 instruction in string?
Sometimes its good to group some instructions...
this code:
mov al,[esi]
mov ah,[edi]
or ah,ah
je .n1
cmp al,ah
jne .n2

is better to see as:
mov al,[esi] mov ah,[edi]
or ah,ah je .n1
cmp al,ah jne .n2

One string - one *functional instruction*.?

Zetus, that leads to pretty ugly spaghetti code... if you want that kind of mess, check out RosAsm.

al=[esi] ah=[edi] test ah jz .n1
cmp al,ah jne .n2

if you like this kind of mess check out Octasm,also Rosasm and the special version of fasm allow multiple instructions per line.
Also take a look to Terse.
