Hi friends, 
I am pretty new to Apex and coming across the following error 'Error: Compile Error: Unexpected token 'global'. at line 7 column 13' whlie trying to save a code to Delete records from a Custom Object called Bookings

I had tried my best but still failing to get over the error.
Can someone please help me in resolving it? I had copied this code from one of Salesforce KB's. 

Use Case: We are looking to call this Class from a scheduled Flow on specific days in order to delete records, as we are short of storage in one of the Sandboxes.

Additionally - how can i add more than ONE object within the same code? so that the deletion operation can work on both objects?

Thanks in advance and any help will be greatly appreciated.

Regards,
Sunny

            delete scope;
