I think the program editor (PE.EXE) in word perfect library might help
you.  I've not worked with files as big as 2 mB (though I think I've
done a couple around 720k).  I believe this editor sets up auxilliary
files on disk to handle overflows (upwards or downwards) when an 
entire file will not fit into RAM.  Of course it takes forever
to load a big file (on my AT with a 28ms. hard drive), and moving down
large numbers of lines is a lot slower than it is for a document which
fits into RAM.  Again, I'm not 100% positive that it will handle
2mB files, but there's a good chance it will.

If you use OS/2, I believe the OS/2 system editor should be able to 
handle big files too (probably not an option for most readers!).
