Does anyone out there know of task switching software which can switch a
program from memory, out to disk, and switch it back in again where it left
off, perhaps even after a reboot.
I want to implement co-routines of around 450k each on a pc compatable
(each coroutine being a separate executable because they are so badly behaved) , so
I'm looking for something at a lower level than MS-Windows, or Bookmark
(i.e. a programmers toolbox/library, not just a user interface).
I would expect something in the form of a TSR which traps an interrupt raised
by the executable giving up control, and swaps it (remembering to take account
of any interrupt vectors that my have been altered by the executable) out
to disk, replacing it by spawning, or swapping another executable off disk.
I don't mind if its a commercial package, so long as it works.
MSWindows will do the job, but all the task switching has to be done by hand,
and I need something automated.
The target machine is a '286 AT compatable 640K under msdos 3.20 .
Thanks in advance.
