Obviously, the OP would learn most from writing this code and not from using someone else's version. But the trouble is that this can extend much further, and it's hard to know where to stop. He would learn still more by writing his own ECMAScript implementation, and a browser to house it. But that needs a good operating system to run on, and he'd learn even more by writing his own OS. Of course a better OS could use a more sophisticated chip-set... and maybe eventually we need to look at genetic engineering. :-) Of course that's facetious [1]. But there is a real point in there. You not only learn more, but you get the results best fitting your individual needs by building things yourself. But the learning curve may be so high that it's not worth the investment of your time. I've built my own bicycles from parts, but would never try with a car. Sure I'd lean a lot, but it's simply not worth it to me. When I have automotive questions that are over my head, I consult with those who know more about it, friends and acquaintances first; paid experts if that fails. Asking in cljs, especially for someone who posts here from time to time, is probably closer to the asking acquaintances end. Unfortunately, I don't have a good recommendation to make, myself. I've used several over the years and never found one I liked. But it was never important enough to me to build my own, either. >> (*)I don't know how to program a VCR. > > A what? In the days of yore, as you have perhaps heard, video data was not streamed across networks, but encapsulated on shimmering discs, called, if legend is correct, deeveedees. But there are stories that in the days of the Old Gods, before the coming of the DeeVeeDee, video was available on a sequential access machine featuring spinning spindles and a lodestone. It is said that these veeceeare machines could record video transmitted magically through the air, but only the wisest of sorcerers knew how to instruct these machines. These sorcerers were known as "geeks", an honorific that survives this day. -- Scott ____________________ [1] Don't you love the word fAcEtIOUs, with all the vowels in order? :-)

That the logic in "if one fully understands" --> "write it yourself" is broken. -- Jorge.

Is there such a newsgroup in the Big 8, or is there such an English-speaking newsgroup, too? If yes, what is its name? TIA.
