Netresults search engine bombs out under my copy of Windows 2000. It works at
home under Windows 95.
(CD) netresults.bat run_me.sh;
The search engine won't run under Windows 2000 or RedHat Linux 7.0.
I have been able to work around this on linux by making sure that run_me.sh
uses jdk118.
I have tried to use jdk118 under windows 2000, but I still get errors, and the
search engine is unresponsive:
please wait until searcher starts on port 6010

Already installed, so starting NRServer....

cannot use search engine under "LINUX OS." The run_me.sh gives errors, |
and cannot find "java/lang/thread."
(Section 1.5.14) In the Learning Perl book, Listing the Secret Words, it says:
Well, the Chief Director of Secret Word Lists wants a report
of all the secret words currently in use and how old they are.
The program discussed in that section does not show how old the words are; it
just shows all the secret words in use.

The NetResults program doesn't work in Windows 2000. I got these messages, but
the port 6010 really doesn't work.

Section 3.2, last two lines |
This is at the end of Section 3.2 of "Learning Perl on Win32 Systems":
print("The answer is ",$a,"
"); # three element literal array
This statement prints "The answer is" followed by a space, the value of $a,
and a new line.
In both lines, I believe $a should be @a.

The code that was suggested didn't work.
For example:
@array = ("140.100.60.79","140.100.60.246","140.100.60.247");
$criterion = "140.100.60.24";
# code snippet from the perl cookbook (cd version)
1: >my($match, $found, $item);
2: >foreach $item (@array) {
3: > if ($criterion) {
4: > $match = $item; # must save
5: > $found = 1;
6: > last;
7: > }
8: >}
With these values it always matched the first element in the array. When I
change the line 3 to:
if ($criterion eq $item) {
it works fine. Is this an error or is it more than one way ...?
(/advprog/ch14_03.htm):
Example 14.6.
font => '-adobe-helvetica-medium-r-normal' .
. '--10-100-75-75-p-56-iso8859-1',
should be
font => '-adobe-helvetica-medium-r-normal'
. '--10-100-75-75-p-56-iso8859-1',
(There are two periods to connect the two strings, one on each line; there
should only be one.)
{Learning Perl, Example 14-1} The line:
$l = $top-->Label(text => 'hello', # label properties
should read
$l = $top->Label(text => 'hello', # label properties
(ie - you've got a --> where a -> is meant). It compiles OK but doesn't run.
{Learning Perl, Section 6.4 Exercises, Exercise 2} The answer given in
Appendix A for this exercise does not appear to match the exercise question.

The code given:
<pre>
foreach $e (@a, @b) { $union{$e}++ && $isect{$e}++ }
@union = keys %union;
@isect = keys %isect;
</pre>
won't produce an intersection of @a and @b correctly if there are any values
repeated in one of the arrays (i.e., if @a = (1,2,2,4,5);, for example).

14.2.2 |
Mail::Send uses the open method to open the mail program for output; it is
built on Mail::Mailer's new method, so that:
# Start mailer and output headers
$fh = $msg->open('sendmail');
serves the same purpose as:
# use sendmail for mailing
$mailer = Mail::Mailer->new('sendmail)';
On the last line shouldn't the ending single quote be inside the right paren?
{Recipe 7.5 of the Perl Cookbook} The following code appears:
for (;;) {
$name = tmpnam();
sysopen(TMP, $tmpnam, O_RDWR | O_CREAT | O_EXCL) && last;
}
unlink $tmpnam;
This doesn't seem correct to me, and I can't make it work. Should $tmpnam be
$name?
