IN Mode
An IN parameter pass the values to the subprogram being called. Within the subprogram, an IN parameter acts like a constant. And hence, it cannot be assigned a value. For illustration, the assignment statement below causes a compilation error:
PROCEDURE debit_account (acct_id IN INTEGER, amount IN REAL) IS
minimum_purchase CONSTANT REAL DEFAULT 10.0;
service_charge CONSTANT REAL DEFAULT 0.50;
BEGIN
IF amount < minimum_purchase THEN
amount := amount + service_charge; -- causes compilation error
END IF;
...
END debit_account;
The actual parameter that correspond to an IN formal parameter can be a literal, constant, initialized variable, or expression. Dissimilar OUT and IN OUT parameters, the IN parameters can be initialized to default values.
