My pattern matching was failing when I had these definitions, which I happen to prefer:
const string number = "[0-9]+"; const string name = "[A-z][A-z0-9]*";
The program is working fine now, after I am using these ones:
const string number = "\\d+"; const string name = "[A-z]\\w*";
Could you please read documentation before posting question?

"w - Any word character (alphanumeric characters plus the underscore)"
Actually I don't think he was asking why w included underscores - I think he was asking why that worked and his original character class based regex didn't. Jerry
