Squirrel Error Messages

Squirrel has many runtime error types pre-programmed. They are largely self-explanatory. However, not all of the errors defined by the standard version of Squirrel are included in the imp version of the language: errors relating to files, for instance, are absent because the Electric Imp platform doesn’t support files.

Here is a list of error messages you may encounter:
