Thanks in advance Smilie
I don't understand. You say you want the last two repeated values and then show three lines of output. The last two repeated values in the sample input appear to be:
Code:
1 7001
1 7002

and:
Code:
1 1002

doesn't appear in the input at all???

Please provide a clearer statement of what you are trying to do!
