I am looking for an algorithm (written in 'C') that
would do demand disk paging from within a editor.
A language processor we are working on only has enough
buffer space available to keep 400 lines of text in
memory.  What is needed is a small routine that will
update the total document on disk, page out the last
least used pages from memory and  then read in more of
the text from the disk ( the reason for all this is that
the system will be run in language labs that have minimum
configuration IBM PC's). As far as I can tell, only
a couple of popular word processors can do this so it
might be trickier that it seems.  If anybody can point
me down a golden-paved path I would be very grateful.
