You don't need to list the classes to link them - you just give the main class and if the others are referrred to and on the CLASSPATH, they will be found. The list of classes is only used for downloading multiple independent programs, selected using the Pgrm button. In this case each program must have a main method.
Worked! Thanks for all
Any problem and I'll come back
