Array1[i] = i*1.5; Print(Array1[i]); prints only cero, why?

I tested several scripts with Arrays assigment and iam a little confused why them doesnt work (them only gets a cero value), for example:

// Channel
   limit=AllBars-ttPeriod-1;
   for(i=0; i<limit; i++)
      Array1[i]=iMA(NULL,0,21,0,MODE_EMA,PRICE_CLOSE,i);               
   for(i=0; i<limit; i++)
      Array2[i]=iMAOnArray(Array1,Bars,5,0,MODE_EMA,i);
   for(i=0; i<limit; i++)
   {

      Print(Array1[i]);  // HERE THIS ONLY PRINTS CERO
                                // EVEN WHEN I ASSIGN A VALUE DIRECTLY
                                // TO THE ARRAY

      Array3[i]=iMAOnArray(Array2,Bars,1,0,MODE_EMA,i);         
      Value1 = 100*Array3[i];
      Value2 = Array3[i] ;
   
      if (Value2 != 0) TS = Value1/Value2; else TS = 0 ;      
      UC = Highest(NULL, 0, MODE_HIGH, i+21, i);  
      LC = Lowest(NULL, 0, MODE_LOW, i+21, i);
      if (TS < 0) Plot3[i]=UC; else if (TS > 0) { Plot4[i]=UC; }
      if (TS < 0) Plot5[i]=LC; else if (TS > 0) { Plot6[i]=LC; }
   }



if i do a simple example it dosent work too:

   limit=Bars-1;
   for(i=0; i<limit; i++)
  {
      Array1[i] = i*1.5; 
      Print(Array1[i]);   // PRINTS ONLY CERO
   }



Any advice on how to solve this problem?

You got to dimension the array before to use it, otherway it will give you zeros.
limit=AllBars-ttPeriod-1;
ArrayResize(Array1, limit);
ArrayResize(Array2, limit);
for(i=0; i<limit; i++) {
. . . .
 
Dear Turcol,

Thank you, it works fine now :)

Is there a place where i can see a language reference for MQ4?

Thanks again.
