Is there a FAQ file on this? I have a load of C from a non-DOS world with about 300Kbytes of code and about 2 Mbytes of data - I can (with some pain) adjust it so that the data space gets allocated by lots of calls to malloc each grabbing 64Kbytes per time, but I can not at all comfortably make my code do anything other than (*p) or (p->component) to grab the data, and I can not predict in advance which page of memory I will touch. It is clear that I could buy an expensive 386 C compiler plus Phar Lap, but (a) I am mean and (b) I would quite like to be able to ship the code I port to others without a large toll or hassle with licenses for DOS extension. Is there a standard route, and do people have experience to relay about (a) the recently announced Lattice 286 development package or (b) using the extended memory support in Windows 3, and what C compilers generate protected mode 286 code to go with same easily. I do noy (yet..) feel any need or desire to implement multi-window mouse driven interfaces, and probably rate reliability of code generated by a compiler ahead of benchmark performance. Since the code to be ported is from a non-DOS world I am not fanatical about specialist DOS interface libraries either - just about the cheapest way of delivering 2 or 3 mbyte applications to customers who have afforded a 286 not a 386 and who MAY be coaxed into buying an extra megabyte or two of memory, which they will need for Windows in due course anyway. Thanks. Arthur Norman
