For identification and information retrieval, you need the program Intkey and data files. You must download and install Intkey first.
In Windows 95/98/NT, Intkey can read the data files from the Internet, and afterwards save them on your hard disk if you wish.
In Windows 3.1, you must download the data files before running Intkey. Download the self-expanding file grass.exe into any directory (folder), and then run it.
