[comp.sys.ibm.pc] Can I get DOS to overlay at spawn

tony@oha.UUCP (Tony Olekshy) (04/11/88)

We have developed an application that uses up most of the memory in a 640K
PC (what else is new).  I wish to start up child processes that don't fit in
the remaining memory.  Is there any way to copy the active process to disk or
extended memory just before a spawn() and then restore it upon return from the
child?  Please mail me, if someone has a good answer I'll post it.  Thanks.

Buy Microsoft windows....
install it on a hard disk system....
Then use the Windows-level function call
to start a new partition.

BANG! you get multiple 640k segments.
