[amibroker] Help with code

["pmxgs" <pmxgs@xxxxxxxxxx>]

Hi,

 I'm having trouble with this code (which was taken from other software):
 PREV is a reserved word that refers to the value of the variable
being calculated 1 period before. In this example it would be
TLevel[i-1]   

 TLevel:= If(C=PREV,PREV,if(prev>ref(C,-1),min(C,deltav),max(prev,C))));

  In Amibroker I wrote:
  TLevel=0; 
  TLevel=iif(C=ref(TLevel,-1),ref(TLevel,-1), IIf( ........

 Can I write this like this?? Or do I have to use for loop??

 thanks
