This demo application is linked to a Paradox data base.
The data base has 5 fields: 2 x,y pairs and a text label. To use the application first press "Open DXF". If you don't open the DXF file first, the application will crash. After opening simply scroll through the data base with the buttons. You can change the values of the x's and t' and the labels. You can also add new records. When you are positioned on the desired record, press the "add line" and/or "add text" buttons. The line and/or text will be added to the DXF file. When finished remember to close the DXF file with the "close" button.
