Hi
I would like to comapre three data file hvng following column
<number><value1><value2>
In three files I would like to check/compare for every matching number in three file both values value1 and value2 must be matched.
so what would be the best way to implement it consider following schenarios ?
1)If any no. present in one or two files but not in third ?
2)If any no. present in one file and not in other two?
(Thugh before comparision it is validated that number is not missing.. )
