Thanks, but I can write, compile and run any Java program from SPF/PC (howbeit with some 'challenges') as long as it contains no "import" of classes etc. All I wanted to know is how to change the default ".java" extension to a 3-char one e.g. ".jav", that's all. I can deal with the rest. Thanks anyway. Cheers, Chris Poncelet
