Evaluation of variables in 50g

[David Hayden]

Note that global and local identifiers behave differently when they don't exist also. If you execute a global that doesn't exist, the calculator pushes the ID on the stack. If you execute a local that doesn't exist, it generates an "undefined local name" variable.

I'm with you, Claudio: I don't see a reason why it works the way it does.
