Consistent with the underlying LibXL library, most of the functions return non-zero for success. For functions that return object handles, e.g. book, sheet, etc., the return value is the handle. For "get property" or "get value" functions, the return value is the property or value. For other "set property" or other functions with no inherent return value, the return value is a boolean, i.e.True for success. The actual error/status codes associated with a failed call may be retrieved with Fn'LibXL'Get'Status(), although this is usually not necessary; see ERROR HANDLING.
