So the behavior of the semicolon is now more consistent no matter what it refers to. I think this is true in version 6 and newer. But your comment about the two semicolons producing side by side plots completely stumps me. I tried it on my Mac with version 7 and it too gives side-by-side (though much smaller) plots of the two planar graphs. If you just put the first DiagramPlot[] command on its own line (without the semicolon) and you get both plots. e.g. << ComputationalGeometry`; nodes = Table[Random[], {20}, {2}]; DiagramPlot[nodes] PlanarGraphPlot[nodes] -Bob
