Can anyone help me with suggestions on how to access extended/expanded memory from Turbo C code? I have a 286 machine, with about 1.6 MB of extended memory on top of the usual 640 kB. I am writing programs that would be much more nice to run if they could access this address space. I think that I have to let the heap allocation routines know about this memory, but it is unclear how to do this. There are global variables _heapbase, _heaptop (I think) that may affect this, but my efforts at changing them generally crash the machine. Please respond to: jfl@hx.lcs.mit.edu Thanks, Jeff Lipton +-------------------------------------------------------------------------+ | Jeffrey F.
