still very useful. Should do your example just fine, and save it to disk between 
symbol runs in a backtest too.

  Herman,
   
  Where are you going with Table functionality?  I ask because I am 
  very interested.  Are you suggesting something like
   
  Column:  Symbol
  Row:  Barindex
  Value:  PositionScore
   
  I'd really love to easily get my hands on porfolio trading info like 
  which positions are on, how many bars ago they were put on as I would like to 
  switch scoring routines based on how long a position has been on.
   
  Have you been messing with any of this stuff????
   
  Kind Regards,
  GaryHerman van den Bergen<SPAN

    size=2>Please forgive my ignorance but I totally seem to miss the 
    significance of dynamic variables... Unless you can convince me otherwise I 
    think I would have preferred to see the introduction of traditional 
    multidimensional tables that can be used in standard math routines...why is 
    this better or more versatile in the field of technical analysis? ... I have 
    lots lots of questions:
    <FONT face=Arial color=#0000ff 
    size=2> 
    1) 
    Can dynamic variables be used to implement multidimensional random access 
    tables, like TableA(k,i,j) ?
    2) 
    Are there any limits to the number of dynamic variables we can 
    create?
    3) 
    Can dynamic variables handle only arrays or also numbers and strings, if so 
    how to define one or the other?
    4) 
    Can we use multiple 'subscripts' like SetVar("VarA"+i+j+k, somenumber) to 
    simulate tradional tables?
    5) 
    Is there any way to save them on disk?
    6) 
    Could you give a non-trivial example/application?
