Who cares? Modern computers are big enough and fast enough to handle everything except editing movies. The ST is a software pattern. Once you learn to recognize it, you can use it over and over by simply plugging in the values. The only thing that changes if the sort-field-extraction functions and whether a '<=>' or 'cmp' appears in the sort. All the rest is just copy & paste. -- Just my 0.00000002 million dollars worth, Shawn Programming is as much about organization and communication as it is about coding.
