hello there, I have a big chunk of data in a file that has got 7 columns(0-7). I would need the first and the third column in some case and the first and the fifth column in other cases. I have no problem parsing the columns. But I need to write them into 24 files depending on the second column,which is from 1-24.


The actual file is something like this: 
10234,1,34234,342,453,34535,3453,3464
12123,1,23432,4353,44645,45654,45645,657
2123345,2,35435,3453,454,56567,56756,567567
3234353,2,34534,4564,567567,56757,56575,24234
33453,3,45464,4564564,45645,645645,54564,56456

I would like to have the required columns of the first two lines in a file and the next two in a separate file and so on for the rest(max 24).
Is there a module to do this? If not how could we open multiple files to write? Is there any easy method to do this?Any suggestions or ideas would be very helpful. thanks in advance.
PS. The files are comma separated and quite big- running upto 5442187 lines in the main file.
