You can do conditional includes as 
  follows:
   
  _N(Chartype = ParamList("Mixed, Price or RSI 
  Chart:","Mixed|Price|RSI",0));
  if (Chartype == "RSI") {#include 
  <Plot_RSI.afl>}
      else if (Chartype == "Price") 
  {#include <Plot_Price.afl>}
      else if (Chartype == "Mixed") 
  {#include <Plot_Mixed.afl>}

  Does anyone know what's the best way to use a 
  parameter to specify which 
  file to #include?  I thought I could use 
  Paramlist, but it appears that 
  #include doesn't accept a string variable.  
  Thanks
