have a char limit, 99 stocks still works for me :-)  Perhaps TJ can provide 
a work around ... I cc'd this to him.

  Re: to HERMAN: N100 Correlation table
  I was 
  extremely intrigued by your matrix, so I tried to run it against my N100 
  watchlist containing 100 tickers (of course).
  <FONT face=Arial color=#0000ff 
  size=2> 
  It 
  crashes with an access violation.   It will run a handful of tickers 
  with no problems, but sure doesn't like 100.
  <FONT face=Arial color=#0000ff 
  size=2> 
  Has 
  anyone else tried it with 100 tickers or more?

      Re: to HERMAN: N100 Correlation 
      tableHerman,There is no need to write the 100 
      tickers. If they belong to WL10, thenlist = GetCategorySymbols( 
      categoryWatchlist, 10 );tickerlist="";for( i = 0; ( sym = 
      StrExtract( list, i ) ) != ""; i++ 
      ){tickerlist=tickerlist+sym+",";}Title=tickerlist;The 
      advantage is that you don't have to correct the code after any N100 
      change, it is done automatically as soon as you correct WL10.Note also 
      that StrExtract()  needs a "comma-separated list of items", 
      that's why the above +",". The result will have a "," at the end, 
      but this is not a problem.Dimitris Tsokakis--- In
