You've mentioned this a number of times, but I don't think you've
explained what you did to the Pascal code to get a 500x improvement.
Was the original code exceptionally bad, was your new code
exceptionally brilliant, did you take advantage of some knowledge of
the VS Pascal code generator or were your changes applicable to code
in any language...?
