Hi, Paul. PE> FA> Just curious why is REGS a union and not a struct ? It feels like one.. PE> Because they want to overlay the word-registers with byte-registers, instea PE> of having them take up extra space. It doesn't feel like a normal PE> structure, because instead of going regs.ax = 5, you have to go regs.x.ax = PE> 5. BFN. Paul. And not just to avoid taking up extra space, but actually to refer to the same memory. So if somewhere you write regs.x.ax = 0x1234 and later on regs.h.ah = 0x56 then you want ax to end up as 0x5634.
