Trying to understand array use

[GrumpyDuckMan]

Hello all,

I am attempting to use arrays to get data.

void TestReadCsvFile() 
// Arrays = OpenPrice,ClosePrice,PriceHigh,PriceLow,PriceHigh,TotalVolume
 { 
   FileHandle=FileOpen(subfolder+"\\GOLD.csv",FILE_READ|FILE_WRITE|FILE_CSV); 
   if(FileHandle!=INVALID_HANDLE) 
     { 
      while(!FileIsEnding(FileHandle)) 
        { 
         Read_CSV=FileReadInteger(FileHandle,INT_VALUE); 
         
       //implicit conversion from 'string' to 'number'
         OpenPrice[0]=FileReadString(FileHandle,Read_CSV); 
        } 
      FileClose(FileHandle); 
      } 
    }

I don't totally understanding how to deal with CSV files to exact information.

Hello all,

I have been reading the MQL4 reference manual relating to array functions. I would like to know if I am on the right path or, am I totally mistaken. 

  void TestingArray()
 {
int MyArrayValue = 12;      // initialize MyArrayValue to be 12
    TA = MyArrayValue;      // move MyArrayValue to TA
    TestArray[0]=TA;        // TestArray[0] value is now 12

// int TestArray[],TA;
// int OpenPrice[],OP; 
// int ClosePrice[],CP;
// int PriceHigh[],PH;
// int PriceLow[],PL;
// int TotalVolume[],TV;
}
