Dear Sirs I have tried some items that seem to hang Mathematica 6.0. However they work perfectly fine in the 5.2 version. I have tried to discover the flaw and I have not been able to do so. The problem pertains at some code I extracted from a book about Mathematica applications by Boccara, particularly the examples that relate to fractals, Julia and Mandelbrot Sets. I have below the lines of code. I you try them, I'd wish to see if you are able to make them work. Yours sincerely, Jesus M, Goiri Clear[JuliaTest] JuliaTest = Compile[{x, y, {n, _Integer}, {c, _Complex}}, Module[{z, num = 0}, z = x + y I; While[Abs[z] < 2.0 && num < n, z = z^2 + c; num++]; num]] DensityPlot[JuliaTest[x, y, 50, -0.75 + 0.5 I], {x, 1.24, 1.27}, {y, -0.13, -0.1}, PlotPoints -> 500, Mesh -> False, ColorFunction -> Hue]
