The application should be installed into C:\PROJECTS folder. Java not older than j2sdk-1_4_2_03-windows-i586-p is necessary. Under Windows2000/XP please execute eprolog.cmd to run the application. Under Windows98 this file should be renamed into eprolog.bat. When started with the program, the root grammar should be loaded first. In order to do that please choose 0-variant in "File" menu, which points to the grammar. With all your questions please contact Vadim Ivanov mailto: artifex@kiberry.ru, artifex@increatum.com
