You can refer to the values of each data series with an index.

For example, if you wanted to add all the closes of 30 data streams you could say:

  MySum = 0;
  for j = 1 to 30 begin
     MySum = MySum + Close of data(j);
  end;

To put these values in an array you could say:

  for j = 1 to 30 begin
     MyArray[j] = Close of data(j);
  end;

You do not have to declare the data series as inputs so to handle a variable number of data series you could say:

   Input: N(30);

   Vars: j(0);

   Array: MyArray[30](0);
  
   for j = 1 to N begin
      MyArray[j] = Close of data(j);
   end;
