Paul,

You know I tried to get it with AMA2() first....

I tried:
value=ama2(cum(1),2,3);

but the returned values did not look correct as what were presented in the email.....I did not think of cum(1) != 1.....

value=AMA2(cum(1) != 1,2,3); // works

Thank you
Anthony

  If AMA2 is

      forward * array + feedback * PREV;

  and das300 wants

      VALUE := KONSTANT + (PREV * Konstant2)
  i.e.
      2 + (PREV * 3)

  you can use        AMA2(Cum(1)!=1,2,3)

  The "cum(1)!=1" is needed to seed AMA2 with 0 as it uses 1 by default.
  If you can suffer starting with a seed of 1, then simply use
      AMA2(1,2,3).

  With those coefficients the series quickly goes asymptotic anyway.

  BTW, there is usually no need to use loops, as AFL is an array-processing 
  language, with an implicit "for( i=0;i < BarCount; i++ )" around every 
  statement.

  Constant1=2;

  Constant2=3;

  Value1=0;

  for( i=1;i < BarCount; i++ )

  {

  Value1[i]=constant1[i]+(value1[i-1]*Constant2[i]);

  }

  Filter=1;

  //AddColumn(Value,"");

  AddColumn(Value1,"v1");
