You can program with the Rational Systems DOS extender and Zortech C/C++ and do malloc()'s of up to 64 K until you run out of extended memory. Which should do it for you. Or you could use expanded memory and the Zortech _handle pointers. This will limit you to 16K per malloc() and dereferenceing a pointer is slower (but nearly transparent to the programmer). But you do have access to expanded (not extended) memory without the cost of the DOS extender. > If not How about Zortec C++, I'm in early development so if I have > to switch I will. Is Zortech better? Yes. :-) -- Zortech mailing list: send email to 'ztc-list-request@uunet' with: Add: your-user-name@your-machine-name In the body of the message. -- Send Zortech bug reports to 'zortech-bugs@proto.com' -- Zortech is my major source of income.
