I need to program a macro that opens a chain of archives that has.in2 extension and for each file, the macro must read the read the data in red (in this example a=248.2926829268 and b=270), and then make a simple mathematic operation c= b-0.5*(b-a), d= b+0.5*(b-a) and then make the following replacement: c=a and d=b, then save that replacement and pass to the next file.


Kindly Regards
