You mean the Ada *compilers* you looked at seem to be slightly slower than the Fortran *compilers* you've looked at. The language itself is not slower, only the implementations you may have looked at. As I said in another post, there's no reason why someone can't put the effort into making an optimizing Ada compiler that's better than any optimizing Fortran compiler. The problem is that some (not all) Fortran compiler writers care about optimization more than your typical Ada compiler writer does. If you compare one of these uber-optimizing Fortran compilers to a random sample of Ada compilers, of course you're going to see a big difference. It would be odd if you didn't. >(Donning abestos suit.) 2 paragraphs too late, I'm afraid. :-) --- T.E.D. homepage - http://www.telepath.com/dennison/Ted/TED.html home email - mailto:dennison@telepath.com
