You can use assignment statements to assign values to variables. An assignment statement contains an assignment operator ":=", which takes the value specified on the right to the variable on left. The script below show you some examples of assignment statements:

PROCEDURE proc_var_2 AS

is_done BOOLEAN;

counter NUMBER := 0;

message VARCHAR2(80);

BEGIN

is_done := FASLE;

counter := counter + 1;

message := 'Hello world!';

END;
