This probably isn't the number exactly but it is in the same ball park, give or take a couple of hundred thousand, that I came across today. It took me a few seconds whether I read it, to work out where the commas might go to make it the more recognisable three quarter of a billion records that I needed to read in.

Bit of a problem really because it entails using things like cartridges, cylinders and all manner of mainframe tricks that I don't really know how to use, let alone have any idea what they are.
