You tried to execute a floating point instruction on a cpu which doesn't support ESC sequences. IIRC, you need a DX series 486 or an SX series 486 *and* a 487 SX coprocessor. Odd, I also seem to recall the 386 was the last series with an optionally separate FPU... Anyway, another option is software emulation. Perhaps, FAQ 11.1 "11.1 Floating-point code without 80387" would help? I.e., it first suggests adding -lemu to your link flags and optionally setting some DOS environment variables (see putenv()). Then, it suggests some software emulators. http://www.delorie.com/djgpp/v2faq/faq11_1.html Rod Pemberton
