Sorry for this mail. I am sure I am not sending to the right place nor in the right way.
Recently I have started to use PSPP in my Windows System and I can't do things I am sure they can be done. Things as Pareto Diagram or combining data files. In manual I can see them, but I don't really know how to do it or where I must write orders. I would be very pleasant if any of you can help me. Thank you a lot and sorry again.
