scripting

When writing scripts using a modern scripting language, e.g. Powershell or JavaScript, where should I define constants? Should I make all constants global for readability and ease of use, or does it make sense to define constants as close to their scopes as possible (in a function, for instance, if it's not needed elsewhere)? I'm thinking mostly of error messages, error IDs, paths to resources or configuration options.
