Hi Jim, It's worked however some cases I got "Use of uninitialized value in join or string at" or "Use of uninitialized value in split at". in both files I have coincident matching keys and I can not have records like these: 
,,,feb,21,5,5

How can I solve this, a simple defined exists would solve this?
