Comparing two files and inserting new fields
Hi all,

I searched the forum and tried to learn from the similar posts. However, I am new and I need to get help on this. I hope an expert kindly help me to sort this out.

I need to compare field 1 and 2 of the first file with the same fields of the second file and if both fields matches insert the field 9 and 10 of the second file to the position 1 and 2 of the first file.
