The Variables options allow you to select which properties of variables you want to view.
Show value type column
Select the Show value type column option if you want to include a column identifying the value type (number, string, or column) in the Variables dialog box.
Show attributes column
Select the Show value type column option if you want to include a column identifying the attributes (temporary, hidden, or promoted) of the variable in the Variables dialog box.
Tip: Having the Show attributes column option selected can be helpful when you try to find out why a particular calculation is not working correctly.
