Please accept my apologies. I am a new user and didn't understand the rules and but I am picking now. On the first post, I want to print out the differences between two files then print out the differences to the third file which I plan to merge the third file with the first file. However, after deep thought, I think I want the code to merge the files after it finds the differences. and skip the diff function. Please give me suggestions or ideas that would help me improve and writer better the code.

thanks so much in advance.
