Ultimately, the distribution is shaped and determined by your distribution function.
In your bell curve, you need to reduce the size of the standard deviation, that is, sigma in the exponent. You can do that fairly simply by simply making the guassian standard deviation sigma an input parameter into your randomizing function. The smaller the standard deviation, the tighter the bell curve. Definately not a perl specific question. -~.-~.-~.-~.-~.-~.-~.-~.-~.-~ -~ -~ Cliff Frensley -~ [EMAIL PROTECTED] -~ Seattle, WA -~ -~ -.
