I still have no idea what you're trying to compare when you're looking at lines from your two input files and I have no idea what output you're trying to produce. Are you just trying to extract lines from your 2nd input file that have a variable_name in the 3rd field that matches a variable_name in the 3rd field on any line in your 1st input file? If this is what you want, it will be easy to write a small, fast awk script to do what you want.
I repeat: Please show us a small, representative pair of sample input files, and show us the output that should be produced from those input files.
