changed "7" to "7.0"; also, in line -6 of the first example, changed
'open MAIL,"|mail' to 'open (MAIL, "|mail'

It now reads:

"can't rename $filename".

Used to read:


(1.2 .. 5.2) # same as (1.2, 2.2, 3.2, 4.2, 5.2)

Now reads:

(1.2 .. 5.2) # same as (1, 2, 3, 4, 5)

Used to read:


(1.3 .. 6.1) #same as (1.3,2.3,3.3,4.3,5.3)

Now reads:

In the 5th paragraph in "Hash Slices" section, line of code used to read:

@league{keys %score} = values %score;

It now reads:

This was a mistake on my part - $line_ should have been changed to
$line (i.e. I incorrectly added a close paren).

after "$line"

So did the period after the "c".

The code was incorrectly changed in the 7/98 reprint to read :

"l" (letter el) instead of "1" (number one). It has been changed to
(letter L capitalized only to emphasize it):

$a =~ /(.)1/; # also true (matches the double L)

of the line, after "hello, world"

The second example from the bottom used to read:

$result = (join "+", "", @fields);

Moved parantheses, so it now reads:

$result = join ("+", "", @fields);

wrong keyword: changed "returns", is "return".

2nd code sample: line 10 used to read:

@result; # return the final list

It now reads:

return@result; # return the final list

changed the last } to ]
