After much controversy, step by announcing that I posted on yahoo groups TDbf PRO https://es.groups.yahoo.com/neo/groups/tdbfpro/info the latest TDbf PRO with what anyone who wants to try you may do so freely so that you can compare with previously on other libs.
The only limitation is that some days will get a warning notice that it is a demo.
Remember it is the only external class to harbor made ​​100% in Language C. I created a method of development to facilitate the creation of classes from C to Harbour absolutely new, just for this and worth studying. : 
RDD controls so any RDD available today can be treated from TDbf PRO even RDDSQL and the like.
I hope any criticism for improvement.
