Hello, The register I don't know are FPAC0-4, CMD, XRA, SSF and FLAG. To be honest with you, I know very little about FFP's. The most I really know about floating point operations is the difference between a float and a double! lol. I am more of an end user and administrator than I am a coder. I am glad though that everyone is so helpful and patient with me.
