Here's a key to the markup:

	[page-number]: serious technical mistake
	{page-number}: minor technical mistake
	<page-number>: important language/formatting problem
	(page-number): language change or minor formatting problem
	?page-number?: reader question or request for clarification


Confirmed errors:


(28) The first footnote starts:
	
	"Perl for Win32 programmers will encounter this mail 
	comand issue frequently...."

"comand" should be "command."


{41} The list of double-quoted string escapes is incomplete. The 
backslash-dollar sign (\$) sequence prevents substition of variable names by
their values.


{56} The double-dot expander in all examples should yield integers, not 
decimals.


{236} Chapter 14, Exercise 1 solution:
The source code yields a script that doesn't execute properly on my system 
(WinNT 4.0 SP5). It appears that \ escaping occurs in a scalar enclosed in ``.

Here's the an example of me running the script and the output:

	C:\Learning_PERL\LP-W32>perl 14-1.plx \Learning_PERL\LP-W32\foo 
	\Learning_PERL\LP-W32\bar

File not found - Learning_PERLLP-W32foo

One solution to this problem is:
  
	my ($src, $trg) = @ARGV;
  	die "$src is not a directory" unless -d $src;
  	die "$trg is not a directory" unless -d $trg;

  	$from =~ s/\\/\\\\/g;  # <------- Insert these substitution lines
  	$to =~ s/\\/\\\\/g;    # <------/

  	`xcopy /s /e $src $trg`;


INDEX:

(271) should include "bail", 199


(273) should include "flock", 199


(275) Remove the "local()" entry.


(276) Add "my()", 105, 131, 229.
