I think I remember reading something about him having two desktop shortcuts....one that actually pointed toward opening the program and the other named differently of course so Hal would identify it, which had a batch file it actually executed and the batch file contained the necessary commands to end the program......that's what I remember..... what suprised me was how ingenious it was, batch files were used all the time in the 'old dos days'
If my memory is accurage he had written some batch files to close popular microsoft programs for people to download......gosh that was a while ago....
