Hi Neil

Thanks for that - that now works for me!

However, (sorry!), the next step, using adaptors, fails when I only include
the
adaptors header file. Source and error attached.

#include <iostream>
#include <iterator>
#include "boost/range.hpp"
#include "boost/range/istream_range.hpp"
#include "boost/range/algorithm.hpp"
#include "boost/range/adaptors.hpp"

void f( int );

int main( )
{
  boost :: for_each(
      boost :: istream_range< int >( std :: cin ),
      f );
  return 0;
}
