As for Colin's objections against writing tight code, he is partially right. I typically try to make my code readable by including delimiting empty lines, or by placing an expression on many lines and aligning its components vertically, so that it is visually intuitive and doesn't require horizontal scrolling. This said, there would be no great formulas (remember Einstein's e = mc^2) if we always tried to expand and make them more readable. Nobody would be able to remember them... $vSeq[index-of($vSeq,.)[2]] is a formula. -- Cheers, Dimitre Novatchev --------------------------------------- Truly great madness cannot be achieved without significant intelligence. --------------------------------------- To invent, you need a good imagination and a pile of junk ------------------------------------- Never fight an inanimate object ------------------------------------- You've achieved success in your field when you don't know whether what you're doing is work or play On Mon, Nov 17, 2008 at 12:53 PM, Michael Kay <mike@xxxxxxxxxxxx> wrote: > Yes, it's an amusing one.
