There is one trick in the Euphoria Programming System,
which allow to lull Windows's vigilance to sleep and 
use system swap-file with the commands of dos32 
interpreter   

You just must to have two programs, the first
is prog.ex and the second is prog.exw

---- prog.ex
integer i
i=system_exec("exw.exe prog.exw", 0)
---- end of prog.ex


---- prog.exw
sequence S
atom N
S={}
N=0
while 1 do
N+=1
S=append(S,N)
end while
---- end of prog.exw

So, if your dos32 program run out of memory,
you can write critical part as .exw program,
call this .exw program from .ex program,
save data, return into .ex program and so on.

Try example above, it works for me and uses
all system memory, i.e. all RAM + all disk space.
