Changing same values in two text files

Hi Everyone,

As a continuation of one of my previous questions...URL below
alphanumeric increment in C[^]

Using the above working code, I open a file, use fgets and sscanf to scan the rows. Each row has a number of items, one of which is a value of 6 characters. The code then "renumbers" it down to 4 characters and prints it out to an output file. What I need to do now is the following:
1. open another, different file, call it FILE2, that also contains the same the 6 character values in a different layout
2. I need to scan FILE2, until I find the one of the 6 character values
3. Then I need to go to the FILE1, find the same 6 Character value and find and store it's matching 4 character value
4. Go back to FILE2 replace the 6 character value it with it's equivalent 4 character value.
