pflynn , Yes you are right, I was doing wrong in defining the array....I thought it will yield me just the col3 value when I compare...but I suppose it was taking whole row and trying to compare...

do you guys explain this part of code , { arr[$1]=$3 } ?

Hi roger67,

Code:
arr[$1]=$3

means to build up an array named by "arr", indexed as $1, its corresponding value is $3.

Best,
