since I do not have any FILE* so I changed it a little bit:

int main( void )
{  
  char word[MAX];

  while( getword2( word, MAX ) )
    {
      printf( "---------->  %s\n", word );
    }



  return 0;
}



static int getword2(char *buffer, int max)
{
  int i, ch;
  
  while ( (!isalpha(ch = getchar())) && (ch != EOF) )
    {
      continue;
    }

  if (EOF != ch) 
    {
      i = 0; 
      --max;
      
      do {
	if( i < max )
	  {
	    buffer[i++] = ch;
	  }
	
      } while ( isalpha(ch = getchar()) );


      buffer[i] = '\0';    /* terminate string */
    }


   return ch;
}

you see the output. It has 3 problems:

1.) it does not discard the words containing anything else than
letters. Rather it discards everything else and read the letters. I simply
want to discard the *whole* word if it contains anything else than 26
letters of English. See the last input where I input your name with junk
between CB and Falconer and it read them :(


2.) Ctrl-D does not do any exit but prints the last word it read :(

3.) thats good point, it discards the letters beyond MAX length :)
