Rootcint and filenames that start with a digit

ROOT

Is it right that rootcint can’t handle filenames that start with a digit?

I’ve tried to find some information about that in the documentation and here in the forums, but found nothing. I do however get errors if the dictionary name starts with a digit (“expected unqualified-id before numeric constant”).

It’s no problem to change the name of the file, I’m just curious whether this is true?

Did you actually try this out? Here are two hints for you:

// a legal ROOT macro named 0.C
{
  cout << "I am 0.C\n";
}
// an illegal piece of C++ code
int main() {
  int 2hundred = 200;
}

Please note, I’m talking about filenames starting with a digit, not variables or other identifiers.
It is perfectly okay in C++ to have a file 0test.cc and compile it (as far as I know C++ doesn’t have any limitations on the filename, that’s all handled by the filesystem).
So what I had, was a command

The file 0testDictionary.cc was however not compilable, due to the fact that rootcint seems to use the filename in places where it shouldn’t start with a digit?
