Is it possible to create a Symbol named `ERC`, `ERC_PHYSICAL` or `$Types$`?

[Werni2A]

OrCad automatically creates a few symbol files in the file container. I.e. it should not be possible to create symbols with that exact same names to avoid clashing names. It would be interesting to see how well OrCad handles this scenario when trying to create a symbol named ERC or ERC_PHYSICAL from within OrCad (same for $Types$). Probably it will just shown an error message or crash...

If anyone wants to test this, feel free to share your findings.
