[Request] Listcombine() - only return common entries
« on: September 08, 2018, 09:25:06 am »

Trying to find a way to extract common entries from two lists - stumped at the moment...

I think an extention to listcombine() is the best (only?!) possible solution - a modifier that when used, combines two lists returning only the common elements in both lists...

I just started playing and I see this is already possible.

This expression:
ListCombine(a;b,b;c,;,;,1)

Returns b.  That's the only common list value in the lists.

So try pushing 1 as the final parameter of the ListCombine(...) expression.
