I need awk to work with two files, read a single column from file1, and taking each value, search for that value in file2.

I guess I need perhaps two forms of "while" loops, one within the other, but cannot get anything to work.

Could anyone give me a simple example to build on?

file1 is created by another process and could have 10 or 20 "codes" that I want to search for in file2 at a fixed position e.g. substr($3,5,4).

Heres hoping someone has done this....
