SPICE and its derivatives (all individual 'wrappings' on the Berkeley SPICE core) are VERY FAST. They work for me just as SPICE works for thousands of other circuit designers, both pro and amateur (I am both). I don't mean to diminish any importance of programming languages or any different CADs or CAEs, but, let's face it, APL is an old high-level language. Unix is an old operating system, yet it still seems to get a whole lot of use. �APL is the ultimate programmable calculator. �It is a beautiful language that can do beautiful things in a very succinct manner. Everyone has their 'favorite' high-level language, each one saying that Their language is the best, most beautiful, and other fancy sayings, complete with all sorts of academic praises and plaudits. My new HP-35S isn't as pretty as the HP-32S II which is also on my computer table and the programming commands aren't quite compatible. Esthetics aside, I wouldn't trade either one of them for SMALL programming tasks. What I want are the numbers from the results so that hardware can be completed. Both do that very nicely for what I want. Perhaps if you actually had used it, you might think more of APL. Perhaps if you had actually used LTSpice, a FREE download from Linear Technology and actually built some circuits using the LTSPice results you might think more of it. shrug Your message appeared in rec.radio.amateur.homebrew and also sci.electronics.cad. I am replying from homebrew. I'm not a programmer despite once having several years complementary membership in the ACM...or teaching myself FORTRAN IV from Dan McCracken's softcover book on the subject. I have MS FORTRAN 5.1 package, bought and paid for myself and have used it for a variety of different tasks...until MS dropped support of their product and also of similar products in later versions of Windows. shrug again If you want to get all arrogant about computer languages, please remove rec.radio.amateur.homebrew from your message routing. In the meanwhile I will continue to do my own homebrewing without going through even-more learning curves of old languages or old OSs just to be with the 'best' tool. Even the 'best' tools can make cruddy circuit calculations. 73, Len AF6AY |
