    Compiling Problem

    My program is this. It will not compile because it says that there is an error with clrscr(). Can anyone help?

    Code:
    #include <iostream>
    #include <fstream>
    #include <conio.h>
    #include "primes.h"
    
    using namespace std;
    
    long primes[1000000L];
    
    int main(int argc, char* argv[])
    {
    	number prime;
       char pf[40];
       long a,counter=0;
       long aaaa=2000000000L;
       cout << "Enter the name of the file to put primes into: ";
       cin.get(pf, 400);
       cin.ignore(80,'\n');
       ofstream outfile;
       outfile.open(pf,ios::out);
       if(outfile)
       {
       	for(a=2;a<=aaaa;a++)
       	{
       		prime.SetValue(a);
          	if (prime.isPrime())
          	{
                clrscr();
          		outfile << a << endl;
             	counter++;
                cout << counter;
          	}
       		if (counter==10000000L)
          		a=aaaa;
       	}
          cout << "\nNumbers found";
          cout << "\nDone";
          outfile.close();
       }
       else
       {
       	cout << "An error occured while opening the file.\n";
       }
    	return 0;
    }

    do
    #include <stdlib.h>

    int main()
    {
    system("CLS"); //clears the screen
    return 0;
    }

    system("PAUSE") just write 'Press any key to continue...' on the screen, it doesn't clear it.
