Henri, My program is in 3 languages , German, English and Dutch. This can be choosen in the program. There is no demoversion, no special support or something like that, but you can always ask by e-mail to me if you have certain questions. The main program calculates flat sundials for any plane at any place in the world. Many sorts of lines can be choosen to calculate. I don't know more types of lines then are in the programs. ( some are in a separate program PLANUUR.) You can calculate a dial to be placed in water as a submerged dial. You can calculate a ( special kind of ) bifilar dial and a mirror dial, also if you want to place them in water. The calculated dial then can be drawn to screen and outputed as an HPGL file. This file can be used in PRINTGL ( also on the disk, an American shareware program ) to print the dial to paper. The file also can be converted to a DXF file for input in Autocad. Then you are able to place figures at the drawing and modify the drawing to your wishes. Some other programs as PAINT SHOP PRO and COREL DRAW can read these DXF files too. There are also programs to calculate a horizontal Oughtred dial or a horizontal azimutal dial and a program to calculate a table for the suns declination and equation of time for a given year. Remember, this is a hobby program, not professional. It is all DOS based, with only a small help file. I assume the users have ( some ) knowledge of gnomonics and patience to experiment with the programs. I am glad that I have heard many positive reactions. The benefits of the sales are for several Sundial Societies, not for me. Order by sending 20 dutch guilders to my adress or buy it via NASS for 10 dollar plus porto or buy it via BSS for 8.5 pounds plus porto. I am a member of the Societies in these 3 countries. Happy dialing, Fer J. de Vries Van Gorkumlaan 39 5641 WN Eindhoven Netherlands.
