I wrote/modified those to do performance testing of the PL/I support that I added to the AEST binary translator. The Fibonacci one was my favourite. It thoroughly worked out a branch look up cache I implemented. Sadly, those figures only really indicated that you were better off running your code on a VAX or Alpha if you didn't have the original source. Gives more of an indication that it might be time to move to a new platform :-( Regards, Tim.
