Don, you are correct.
1) The input might not be same only in adjacent lines
2) The list is comma separated and when I checked with some tweaks in the inputs , it produces duplicates in the output list.. Which I mentioned in the first post that it should add uniquely. So, I dont need duplicates in the list.

Many thanks once again.
Note that if you want the lists combined by my script to use just a comma to separate entries in fields 4 and 5 instead of a comma followed by a space, change the following line:
Code:
                if(j >= i) os = os ", " a[j]

to:
Code:
                if(j >= i) os = os "," a[j]

Note, however, that the script won't change the lists unless two non-empty lists are found for the same field for the same value in the first field. It could be made to normalize all lists found, but it would run slower.
