Problems Under Windows/DOS

When I run the JRE command I get a message saying the file Prolog.zip cannot be found.

In the JRE command -cp Prolog.zip is telling JRE where the file Prolog.zip is. The safest way to ensure that is right is to type in the full path. So if you put Prolog.zip in c:\greg\prolog then use -cp c:\greg\prolog\Prolog.zip in the JRE command.

When I run the JRE command I get the message that the class can't be found.

Java is case sensitive and so in the start command prolog.dgks.Prolog_1_02 must be typed in exactely. This is the name of the Java class that starts the program.
