parallel computing sig problem

Hi:
I have a for-loop, which is very long (over 500 line for example). now I'm able to optimize it into parallel computing.
the problem I'm having is that, I want to add a input as parallel sig: par_sig, to control if the code will do parallel computing. if par_sig=1, do parallel computing, if par_sig=0, do normal loop compution.
when this go to the code, it becomes:
if par_sig==0
for ...
500 lines operation...
end
elseif par_sig==1
parfor
500 lines operation...
end
end
in this way the same 500 lines code are written twice in the code. if I revise somewhere I'll have to do twice also, which makes the operation very boring. is there anyway, or any trick, to write it only once?
Thanks!
Yu

So, you simply cannot put those 500 lines of code inside a function? Or if not as a function, as a script m-file?
There is absolutely no need to copy the code and thus replicate it inline.
Essentially, you can just put it into a separate m-file. Call it my_code.m. Save that as a file. You would then call it essentially like this:
if par_sig==0
for ...
my_code
end
elseif par_sig==1
parfor
my_code
end
end
Now you can make any changes just once, editing the my_code function/script.
