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
