The changed was done in colum 38, value 2 has been replaced by value 1, acoording to file datatochange.txt $5
looking and taking as reference 2657.00 7305.00

In the reference file datatochange.txt, I have wrote the name of the file where the changes need to be done. the output name for the new file need to be different. (sw1135gnew.xps example)

I have many files to change it is only a example for one case.

Please let me know if there is other way to do it,

Any help on this will be strongly appreciated.

Thanks in advance :)
