1st and 2nd paragraph |
in "Alternate Method Searching": You said that perl search for methods by browsing the @INC array.
I think you meant the @ISA array, not @INC.
Thanks for the book, because I never understood OOP like I did now.

On page 117, there is code that looks like this:
for ($i = 0, $bit = 0; $i < 32; $i++, $bit <<= 1) {
print "Bit $i is set\n" if $mask & $bit;
}
#the values in $i and $bit persist past the loop
This was an excellent example of how global declarations work, as it was
intended. The only problem is that $bit is initialized to 0, so the loop
will never produce any output because $mask & $bit will always evaluate to
0.

Example code |
Provided code example doesn't compile. The following
select((select(TO_CHILD), $| = 1))[0]); #autoflush
select((select(TO_PARENT), $| = 1))[0]); #autoflush
should be
select((select(TO_CHILD), ($| = 1))[0]); #autoflush
select((select(TO_PARENT), ($| = 1))[0]); #autoflush

substr entry |
For your Larry and Moe examples, you say:
"To prepend ... to the current value of $_ ..."
and
"To instead replace the first character of $_ with ..."
but $_ should be replaced with $var in those statements.

Entire index and TOC |
Hi
There is no "linking" in this book. You can't click an entry in the TOC or the index to jump to a particular page. This is such a pity. The index is absolutely brilliant, but is unusable without the linking.
This is a feature that is pretty standard in PDF books. If this can't be corrected, then it should be highlighted before people buy the book. What about including some indicator to show the level of linking that has been included e.g. 0 for none, 1 for TOC, 2 for TOC and Index, 3 for everywhere possible.
Cheers
Mark

You have the following entry in the table:
declared as:
sub mysplice (\@$$@)
called as:
mysplice @array, @array, 0, @pushme
But actually I think it should be:
declared as:
sub mysplice (\@$$@)
called as:
mysplice @array, $offset, $length, @pushme
or something like that. I'm not sure about this, but I think that would help it align with the splice function better. More importantly, the 2nd item right now correlates @array with $, which seems to be wrong.

This is the index entry entitled recursion of subroutines and there is no page number given.

2nd @reflist statement in the middle of page |
A comma is missing (a space printed instead) after @a in the line
@reflist = \($s, @a %h, &f); # Same thing

The errata pages for this product have suddenly been reset so they say there are no errata. That is simply not true. There is no new printing listed that would have justified this change.
I tried to submit something using the short form on the book page, but it caused my firefox 3 browser to display html source instead, so that component of your web pages is broken as well

__PACKAGE__ does not appear in the index. Other "double-underscore"
keywords do appear (e.g. __DATA__, __FILE__, etc).

4th Paragraph, starting "To look at a windown of source code..." |
It is stated that the w command will list a "window of code" around the current breakpoint. This is incorrect.
The w command sets watches on variables.
It maybe that the author is trying to show is the use of the l command.
The example code following also shows the wrong command being used.

Section on Tracing, explanation of W |
The description of the W command says that this sets or deletes watches. This is an error.
Lowercase w sets watches while uppercase W deletes them.
