on positional_options_description - "specifies translation from position to name".

So I am not sure if you mean you want to only add more than one value -

which the tutorial very well explains;

or add more than one value to the same position - which would be absurd.

For code like:

=============================================

optdesc.add_options()
     ("input-files-1,i", po::value< vector< string > >(&input_file_1),
         "Input file name." )
     ("input-files-2,i", po::value< vector< string > >(&input_file_2),
         "Input file name." )
     ("input-files-3,i", po::value< vector< string > >(&input_file_3),
         "Input file name." )
;
po::positional_options_description posopt;
posopt.add("input-files-1", -1);
posopt.add("input-files-2", -1);
posopt.add("input-files-3", -1);

all positional values given at command line would be

assigned to "input-files-3".
