The website listed here for getting code examples and downloading the packages
references is WRONG.

Note at bottom of page

The code segment for Oracle 7 or Oracle 8 does not seem to work as shown:

CREATE OR REPLACE PACKAGE book_data
is
total_count INTEGER(10);
SUBTYPE total_count_t IS total_count;

For this to work for me in Oracle 7.3.2.2 I did:

CREATE OR REPLACE PACKAGE book_data
is
total_count INTEGER(10);
SUBTYPE total_count_t IS total_count%TYPE;

Should read:
FUNCTION daily_fine RETURN NUMBER;

Example code

The variable l_one_day_fine is not declared or initialized in the code.

Additionally, in the fixed code on page 57, l_overdue_count is not
initialized prior to processing the loop, so the page 57 code is not
equivalent to the page 56 example.

First Loop Exit When statement

The correct syntax of emulating a REPEAT UNTIL Loop specifically
LOOP
EXIT WHEN statement is

LOOP
... body of loop ...

EXIT WHEN boolean_condition;
END LOOP;

However, in this example,
The EXIT WHEN clause is placed right before the body loop. A
know catchable-syntax-error descriptions generated by Oracle could be
something like this:-

ERR *
PLS-00103: Encountered the symbol "INTO" when expecting one
of the following: . ( * @ % & = - + ; < / > in mod not rem
an exponent (**) <> or != or ~= >= <= <> and or like
between is null is not || is dangling

Solution:
After I placed the EXIT WHEN clause right before the END LOOP
statement, it ran without giving me any errors.

Example function book_title in middle of page

several typos in this function

An extra space is in "l_title"
---------------------------------
IS
l_ title book.title%TYPE;
BEGIN

the above should be

IS
l_title book.title%TYPE;
BEGIN

The RETURN in the BEGIN section is wrong
-----------------------------------------
RETURN l_rec.title

the above should be

RETURN l_title

second bullet in top third of page

you refer to DBMS_UTILITY.FORMAT_CALL STACK

it should have an underscore between CALL and STACK

that is DBMS_UTILITY.FORMAT_CALL_STACK

line 15: SELECT title INTO l_title

The code does not compile as is.
l_title is not delared.
line 15 should read instead:
SELECT title

Sample code on top of page 101 looks flawed as it should relate to the sample
code on the bottom of page 100
