Version 6 no longer generates plots as a 'side effect'. Greaphical output is now regular output just as everything else. So you now need to remove the semicolon to obtain the output. Mathematica was trying to give you a hint of that by coloring the semicolon red. So how do you generate a plot as a side effect? Again, your question contains the answer. Just put the plot statement inside of a Print statement. -- David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ "Charlie Brummitt" <cbrummitt at wisc.edu> wrote in message news:g2b4nj$nlf$1 at smc.vnet.net... > Hello, > I am running into difficulties with Plot.
