Hi,

Let's imagine that we have a text file with the following format:

1 ____ 100.00
2 ____ 200.00
3 ____ 300.00
.....
There is blank space (represented by the underscores) between the integer numbers in the first column and the double numbers in the second column. Is there any way of opening such a text file and assigning the values to a U++ Vector<int> and Vector<double> containers? In standard C++ (using C++ streams and operator >>) this is simple but how can it be done using U++ Streams (FileIn)? do I have to overload operator >>? is there any simple way of doing it?

Many thanks,

Javier
