TIP The first version was a freeware and was fully dedicated to the teaching of variographical analysis. The copyrights however did not allow the distribution of the freeware without the agreement of the author. This explains why Variowin was not available on the web. A commercial version has been released later with a book which was an improvement of the online help. The book & software have been sold together and are now currently out of print. VARIOWIN 2.21 is now the latest version of the software and is free.

Problems & Bugs

If running Variowin 2.2 under Win95, be aware that the DOS restrictions on file name length still apply. When trying to save a *var file for example, if the file name is too long, there is no error message but it does not save the file.

Version 2.21 of the software fixes the floating point error .
