Yes! You need to link a piece of software called a "DOS Extender" into your application. DOS Extenders allow your protected mode, 32 bit application to make calls to humble real mode software sitting in low memory. The humble real mode software to which I refer inludes DOS itself, as well as our IPX code. Using a DOS extender, you should be able to devise a way of using the IPX far call interface we provide. I'm uncertain as to whether you could use our CLIBS as they get linked into the app along with the DOS extender! All they actually do is hide the assembler interface anyways. Zortech might be able to sell you a DOS extender along with the compiler. They might even have one in the product. Otherwise, try calling Quarterdeck Office Systems on 213 392 9851. They are the real experts on playing tricks with DOS memory.

There are a couple other companies that provide similar extenders, but I'm not at all familiar with them. Sorry, but I don't have the number for Phar-Lap. I suspect they advertise in Computer Language Magazine or other such programming journals. Actually, Zortech might be able to suggest something or include something with the package. I think MetaWare does include a DOS extender with their 32-bit compiler. -- Skip

I can confirm that the Phar Lap extender works on NetWare client systems, althought neither Phar Lap nor Novell supports it. We've got Mathematica 386 (a 3 Meg+ protected-mode program) available on our software server. It uses Phar Lap's 386|DOS Extender, and it appears to work with no problems. The only caveat is that the overlays page a little slowly, but it's not too bad since we have it configured to do data paging to the local hard disk. Not all DOS extenders will work; the differences may be on an application- by-application basis. For example, Turbo Debugger 2.0's 386 debugger will _not_ work when I am using NetWare. (The 286 debugger works fine!) -- Stephen Trier Case Western Reserve University Work: trier@cwlim.ins.cwru.edu Information Network Services Home: sct@seldon.clv.oh.us %% Any opinions above are my own. %%
