I have been experimenting with APL and have come up with a few questions that someone might be able to help me with. What do I use for negation???!!! Minus is shown in the equivalent char- acter set, but negation is not to be found. I have tried a few plausible things with no luck. By the way, in an attempt to solve the above problem, I went hunting in the source. Where the *&$@!~*^#!!? are all the comments? As I understand the situation, there ARE no comments! I would like to see a really well commented source listing, not to modify, or find implementation "features" in, but just to see how an APL was done. In exchange for proof of licensing, plus what ever other restrictions you might wish, can anyone let me see a source with comments? One last thing. Has someone got a discrete Fourier transform function written in APL? I am looking for something with 2*n data points, maybe with inverse DFT thrown in. I don't need terrific speed, or huge data sets, just something simple. It looks like a few counters going different ways, driving a restructure operator, with a butterfly function should do it. If someone has a library of relatively simple things I could learn from I would be very appreciative. Many thanks in advance Don Taylor
