Using DEFAULTYou can use the keyword DEFAULT rather than that of the assignment operator to initialize the variables. For e.g. the declarationblood_type CHAR := ’O’;it can be rewrite as follows:blood_type CHAR DEFAULT ’O’;Use DEFAULT for the variables that have a typical value. Use the assignment operator for the variables (like counters & accumulators) which have no typical value. Some of the examples are shown below:hours_worked INTEGER DEFAULT 40;employee_count INTEGER := 0;You can also use DEFAULT to initialize the cursor parameters, subprogram parameters, and fields in a user-defined record.
