I am not sure what do you mean saying "by using counters". Once the table is created, you can reference it by ".",e.g. T.Name, T.Age. See "help table". There is an example data, run the example and check out patients.Age, patients.LastName, etc.

Thank you very much. About counters, I mean using nested for loops to compare two variables' data. I wanted to connect two columns in the dataset with each other(two variables in the table T) to form the edges between nodes.
