Positional and Named Notation
You can write the actual parameters when calling a subprogram, using either positional or named notation. That is, you can point to the relationship between an actual and formal parameter by the position or name. Therefore, the given declarations are:
DECLARE
acct INTEGER;
amt REAL;
PROCEDURE credit_acct (acct_no INTEGER, amount REAL) IS ...
You can call the procedure credit_acct in 4 logically equal ways:
BEGIN
credit_acct(acct, amt); -- positional notation
credit_acct(amount => amt, acct_no => acct); -- named notation
credit_acct(acct_no => acct, amount => amt); -- named notation
credit_acct(acct, amount => amt); -- mixed notation
