Chris recently mentioned that much of what he writes in regards to how LB works in the background is just speculation wink

Well indeed it must be, since only Carl knows what actually happens (and even he may not always know if it's buried within SmallTalk). Similarly any comments I make on the internal workings of LB are just intelligent guesses based on the symptoms and experience gained from writing LBB.

But in this case Chris was referring not to the internals of LB but to the Windows API. Claiming that many Win32 APIs support only a 32-bit file-size is, I'm afraid, plain wrong. Yes it can be easier to use a 32-bit size value, and I've done that many times myself (indeed it was a limitation of LBB pre v3.00), but it's not actually enforced by the API.
