let's say I have this example, how to add it, so that it could be displayed later on with gui inside textflow window? :
List<String> Test1 = ["a", "b", "c", "d"];
List<String> Test2 = ["1", "2", "3", "4"];
Output should be like: ("actual output, each on a new line")
Line = "a1";
Line = "b2";
Line = "c3";
How to do this? Thanks in advance.
