My appologies in an attempt to be brief and to the point...I have made my question too vague. This is what I am doing. X one of many ID numbers. I want to loop through my file and write it to a second file checking the ID number on the way. For every UN-unique instance of the ID (say it appear 10 times throughout the file)I want to increment it's sequence number So the output might look like this ID SEQ 1 1 1 2 2 1 3 1 1 3 My problem is I just am not good enough to understand how to accomplish this unless all ID 1's were consecutive and all ID 2's were consecutive etc etc etc. aschroh
