Did you believe it? >;) Well, hmm... This is what Richard Lang (um, and you) told me when I asked this question last year. Something about not being able to access more than 64K of memory at a time except by some sort of paging scheme. In other words, the Palm treated its internal memory more like disk storage than flat memory. I admit that I didn't confirm this independently. I thought Richard would know what he was talking about. In any case... WOO HOO! Hash tables on a Palm! Now I have an excuse to upgrade my 2MB PalmIIIe!
