I found it simpler than CSVDocument (which anyway I discovered later)
because I can setup everything in the form designer and I only have to
change che filename I need at runtime. A simple call to
copyfromdataset will then copy the real data to the working dataset.
Finally, when everything is done, I use a TCSVExporter (also
completely filled in at design time and bound to the working dataset)
by calling its Execute method.

Very selfishly, If you drop the fixed length support, I won't notice
it; while if you rename the TSDFDataset to a TCSVDataset, then I have
to tweak & rebuild a few bit-tons of code.
