Error when using string pointers

I have writtena function to display string of characters using pointer but it shows error. can anybody what is the error in it?

void WriteString(char *Buff)
  {
     int nStringLength;
     int nLoop;

     nStringLength = strlen(Buff);

     for(nLoop=0;nLoop<=nStringLength;nLoop++)
        {
           SBUF = Buff(nLoop);
          while(!TI);
          TI = 0;
        }

     Delay(50);

     return;
   }

when compiling there is a error pointing the line,

SBUF = Buff(nLoop);
The error is,

Error C211 : call not to a function
Error C208 'function':too many actual parameters.
