Thanks Paul

Problem is solved but I will certainly look into your code.
Might learn something.

Hi Bo,

I wrote a routine called “ListIntersect”, which I’ve posted on GitHub.
We originally wrote it in Omnis Studio 3, but it’s up on GitHub in
Studio 8 format.

Basically you use it like this:

Do voListInterection.$ListIntersect(plList1,plList2,psFieldname,psFieldtype)

IN:
* plList1 – the larger of the two lists to process. It can have
duplicate values in the column that you’re testing
* plList2 – the smaller of the two lists.
* psFieldname – the column name in the list that you’re comparing again
* psFieldtype – options are Char, Int, Num or Date.

OUT: All lines in list1 that exist in list2 will be selected in list1.

NOTE
Both lists will be sorted by the nominated field name.
The comparison column must be the same name/type in both lists.

You can download the code here:

Regards,
Paul.
