In C++ that would be:

string V1 = "1234567890";
string V2 = "AAA" + V1.substr (2, V1.length() - 3) + "BBB";


It isn't better, but I don't really think its much worse either. The only real
problem is that we are working with stack objects in Ada, whereas the C++
version is almost certianly involving dynamic allocation and deallocation.
