Optimized for speed, optimized for memory requirement, optimized to handle extreme situations, optimized to handle easy situations? You can try explaining "optimized" to a human being. Then try to eplain that to a computer program. Josef -- These are my personal views and not those of Fujitsu Technology Solutions!

Maybe also predict the future so that it can optimise appropriately for the actual use of the code? Have you actually bothered to read /anything/ that has been posted in this thread? We've used your wishful thinking as inspiration for some interesting discussions, but no one considers your mythical tool to be at all realistic. And your response is "for my next wish, I'd like three more wishes".

A friend of mine (and, as far as I can recall, the only genuine rocket scientist I know personally) once recounted a (true) story where he had to optimise his code for temperature. When people describe an impressive program as "cool", he sometimes allows himself a wry smile. -- Richard Heathfield <http://www.cpax.org.uk> Email: -http://www. +rjh@ "Usenet is a strange place" - dmr 29 July 1999 Sig line vacant - apply within |
