Even then, I'm lucky to get 4 meg free :).. and I know Hdd's cost 50c/meg
but I still don't have the money to get it.. :)

Multiple passing??.. I was originally thinking of a method where you read
in a block, sorta that then got the next line read the same sized block or
something like that.. I was just wondering if there was a way to do it
without using EMS/XMS..  although hopefully I should need to use  the
sorter, so I might get you to compile it for protected mode for me if you
could, because not many people run a BBS with less then 4 meg :)
