I'm writing an application in Turbo C++ which requires large data structures,
ie an array of dimension 1,500,000 bytes (to hold a 512 x 512 image in real
format). I thought I could use farmalloc to allocate a large chunk of memory
and then use ponters to store and retrieve the data. The problem I encounter
is the lack of memory access to memory above 640K. Can Turbo C++ make use of
extended memory other than for overlay swapping? Is there a solution with
Turbo C++ ? If not How about Zortec C++, I'm in early development so if I have
to switch I will. Is Zortech better?
