Re Mathematica 6.0 under WinXP. The code below works as planned, except that a red marker appears between the final ) and ], announcing that more input is expected. I'm presuming that in this case, the marker can be ignored, but want to doublecheck with others. Thankx. Bruce Needs["Quaternions`"]; w={3,4,5}; u=w/Norm@w; Quaternion[Cos[Pi/4],Sequence@@(u Sin[Pi/4])]
