Hello all,


   I have a tricky algorithm question.  I am programming under Windows but
can possibly make my application a DOS executable.
   I'm dealing with a table the is larger than 640k.  I need some code or
ideas on how to do effcient page swapping.  Access of the table is in no
particular order.  One access my be in the first 20k and the next access may
be up past 2mg.  The data cannot be sorted to make the access any better.
   I was hoping Windows might have some extended memory support to let me
get more pages into memory at once.  I have considered using a ram drive to
store pages and retrieve them quickly.
   If you have an ideas please respond by email.
