prime.exe is a gcc file that reads a 866 gig file of primes < 3 trillion.
 
Too bad we can't open and read files in the calculator like in C. I have to use
this to read my list of primes.
 
prime2(n) =   \\ the nth prime using c:\sieve\prime.exe in the path calling
                   \\  m:\sievedata\prime2-3trill.bin" 
              {
              local(x,s);
              n=round(n);
              s=concat("prime ",Str(n));
              extern(s);
              }

cls.bat clears the screen in gp. It also places the cursor at top LHC and the
scroll bar to the top. 
 
put this in util2.gp
cls() = system("cls.bat");
must include the bat
 
extern("cls.bat") does nothing here either.
 
At first, I thought forcing the simicolins after each line was ok but I really
don't like it any more. I like the old way much better.
