Sure, you'll have to pay for it, but it's structured better for what you want to do, and more accurate to boot. I was recently told that the non-commercial NEC-4 license doesn't include source code. I haven't confirmed this, but it's something you should investigate before purchasing an NEC-4 license if you intend to modify the source code. You'll also, of course, need a Fortran compiler capable of compiling a multi-threaded application. Roy Lewallen, W7EL I have a non-commercial license, and it came with NEC 4.1 FORTRAN source code. Frank I'll jump in here without knowing much about the program, but in general having the Fortran source code doesn't do much to solve your problem. The function calls to the run-time system is where the problems will occur. Unless there are versions that support multi- processors, you are still screwed. Paul, KD7HB |
