I know 
actually the IsNull() etc ... functions, but I need also a mean to test a null 
value in a for loops. The code was just given as a simple 
example.

  Jerome,
   
  You don't need to go through the complexity of 
  a FOR loop.
   
  test=<FONT 
  color=#ff0000>IIf(<FONT 
  size=2>IsNull(mo),1<FONT 
  size=2>,0<FONT 
  size=2>);
  Plot<FONT 
  color=#ff0000>(test,"Null=1"<FONT 
  size=2>,colorblue,1<FONT 
  size=2>);
   
  There are several functions for testing presence 
  of valid data:
  IsNull
  IsEmpty
  IsFinite
  Nz
  IsNaN
  IsTrue...

constant
    
    <FONT face=Arial 
    size=2>Hello,
    <FONT face=Arial 
    size=2> 
    Until yet, I 
    have not succeeded in using the "Null" constant in for loops. In the simple 
    following code, I would have expected the first 5 bars of the "test" 
    array to hold a "1" value. This is not the case, so the expression (mo[i] == 
    Null) does not return a true result even when the MA(C,5) doesn't return any 
    value. Is this by design or do I use this constant in a wrong way 
    ?
    <FONT face=Arial

    Thank you in 
    advance for any piece of help.
