All system's memory - this is RAM (yours 16M) and swap-file.
Swap-file is system's one if this is OS's swap-file.
On plain DOS (reboot in msdos mode) Eu has *own* swap-file,
because of the plain *msdos mode* has *no* the system swap-file.
On Windows, only system swap-file exists and Windows uses
this swap-file to *free only RAM* (yours 16M) for your dos32
Eu program.
Just run you program after rebooting in msdos mode and
Eu will use *own* swap-file to the end of the free disk space,
if 16M is too little RAM memory for your program.

Yes, Bernie is right, if you run pure msdos mode.
But If you run dos32 program on 'windows in the background',
your dos32 program has only all system RAM (yours 16M),
without swap-memory-space.
This subject was discussed in our list in the past,
I can add my answer to Florian for detailes. See below.
<-------
Dear Florian,

Try please
---------
sequence S
S={}
atom N
N=0
while 1 do
N+=1
S=append(S,N)
end while
--------
This program must be for DOS32,
file with .ex extention, and run
in DOS window on Windows.
This program will occupy the whole
of RAM and stops with the error
message and the ex.err file.
In file ex.err, you can read
maximum N.
It seems, Windows doesn't allow
swapping of DOS32 programs
and swaps only own code and data.
You can see my results and test
program in the attachment.
On Windows 95 in DOS window,
N was 834907 with 8M RAM
and 14M of the free disk space.
On plain DOS32, N was 1630691.
On plain DOS32, when swap file
was blocked with option
set causeway=NOVM (in autoexec.bat)
N was 834907, same as on Windows 95.
------->
But, John, if your dos32 program is not *graphics*
one, you can try just rename the extention from
.ex into .exw and run it under exw.exe control
on 'windows in the background'.
Then it will use all *system memory*,
i.e. not only all RAM, but + all disk swap-space.
Attachment's program (same above) with .exw
extention uses all *system memory*.

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. Regards, Igor Kachan kinz at peterlink.ru
