Er no, but for the most part a Program written for Perl 4 should run
unchanged with Perl 5 - there are a couple of gotchas but these are
described in the perltrap manpage.

If the problem with is caused by the different bugs in various browsers
then it is unlikely to be a Perl problem - I would suggest that you ask
in a group interested in browsers or make a bug report to the vendor of
whichever browser you dont think is behaving correctly.

The reason is that system must wait for the process to terminate before
the script can proceed (the return value of system is the process's exit
status).
Is there a reason not to do this via shell script?

No, I could do this with a shell script.; However, I am trying to teach my
self a little perl and thought this may be a good way to do it. I thought
there was some way to spawn a process, basically kick off and let the OS
worry about the exit status.

Well, you asked 'Can I do it...', not 'How can I do it...', so some wise
guys answered what you asked. I think you are owed an apology and a
straight answer.

Look for ActivePerl; download and install it. I have found it to be
very clean and neat, and trivial to install.

Yep. Using the activestate version you should have know trouble - infact
it is a slight improvement over Win95 as you dont have to install the
DCOM thing as it is already there.

I think that a discussion of the relative performance merits of databases
would best be taken to some comp.databases.* newsgroup really.
All of the above mentioned systems work well with Perl and it is really
to do with the implementation of the database server that is pertinent.

How do I fork a daemon process?
If by daemon process you mean one that's detached (disassociated from
its tty), then the following process is reported to work on most Unixish
systems. Non-Unix users should check their Your_OS::Process module for
other solutions.
* Open /dev/tty and use the TIOCNOTTY ioctl on it. See the tty(4) manpage
for details. Or better yet, you can just use the POSIX::setsid()
function, so you don't have to worry about process groups.
* Change directory to /
* Reopen STDIN, STDOUT, and STDERR so they're not connected to the old
tty.
* Background yourself like this:
fork && exit;

Good question. Sometimes `-t STDIN' and `-t STDOUT' can give clues,
sometimes not.
if (-t STDIN && -t STDOUT) {
print "Now what? ";
}
On POSIX systems, you can test whether your own process group matches
the current process group of your controlling terminal as follows:
use POSIX qw/getpgrp tcgetpgrp/;
open(TTY, "/dev/tty") or die $!;
$tpgrp = tcgetpgrp(fileno(*TTY));
$pgrp = getpgrp();
if ($tpgrp == $pgrp) {
print "foreground\n";
} else {
print "background\n";
}

Use the alarm() function, probably in conjunction with a signal handler,
as documented the section on "Signals" in the perlipc manpage and
chapter 6 of the Camel. You may instead use the more flexible
Sys::AlarmCall module available from CPAN.

Yep thats the way that exec works I'm afraid - it replaces the current

What you are looking for is one of system() or the backticks or even
possibly the creation of a pipe using open(). You should read the perlfunc
manpage to determine which is more suitable and perhaps also perlipc.
However a quick synopsis:
$rc = system('a.out'); # a.out is run an its exit code is returned
$output = `a.out` ; # a.out is run and its output is returned
# exit code is in $?
open(AOUT,'a.out |') || die " - $!\n"; # a.out is run and its output is
# available to be read through
# the fielhandle AOUT

Generally Matts programs are held in very low esteem around here for
various reasons that are recounted so often that I dont think I need
repeat them. If it works for you I am very happy however.
The problem is here that it is generally considered poor taste to be
asking here for support on these things and especially as the majority
of the people here are unlikely to have the source code lying around.
The best approach would be to examine the code and discover where the
output is generated and then alter that so any output text containing the
search term is emitted in the appropriate manner to make it appear bold.
This might be as simple as putting:
$output_text =~ s|($search_string)|<BOLD>$1</BOLD>|g;
somewhere in your code. But somehow I doubt it.
Go ahead and try a few things and if you have any difficulty with the
Perl aspects then post the tiniest snippet that demonstrates the problem
so we might better help you.

is that there are some commas within quoted strings which I don't want
the split function to recognise and split at.
Is there any way (or module someone has written) that can help me split
the strings into lists while ignoring the quoted commas? I have tried
all manner of substituion combinations, but nothing seems fool-proof.

It appears that the linker requires you to explicitly tell it to use
the maths library to get those functions. You will need to start the
configure process again and when it asks you if you want to specify any
additional libraries you should type in the name of the maths library
most probably -lm as well as all of the ones that it suggests.
This is strange however because I built Perl on a similar platform the
other day and it went alright (once I had sorted out the dynamic loading)
are you sure that configure guessed the OS right ?

It is unlikely that this can be done as in all likelihood the mail sending
will occur asynchronously after the data has been handed to sendmail.
Most sendmail configurations will wait for some pretermined period before it
determines that it cannot send the message unless it encounters some fatal
error on its first attempt that would mean a retry is useless.
If it is at all possible it is likely that it something that will have to
be done to sendmail rather than in your program. I would suggest that your
first port of call should be the sendmail manpage or a newsgroup that is
concerned with sendmail issues.
A possibility would be to create a second script that would be called from
procmail that would catch the 'bounce' messages and do something appropriate
but this not going to be something that you can do within a CGI program.

I may have misinterpreted your question. By a "simple text file" do you mean
that the output is text, not html or that the script is showing? If it's the
former, my answer aplies. If the latter, then either you didn't chmod the
script to be executable, or your server is misconfigured.

Two popular editors are The Programmer's File Editor (PFE)
http://www.lancs.ac.uk/people/cpaap/pfe/
and Emacs for Windows
http://www.cs.washington.edu/homes/voelker/ntemacs.html
PFE does not support syntax highlighting and does not have a special
perl-mode. Emacs has both syntax highlighting and a special perl-mode.

Missing maths library - you will need to explicitly add it during
configure when it asks you for the additional libraries. And if you havent

This splits an arbitrary string into pairs of characters, allowing for
an odd number of characters. If you want to restrict to 'pairs of
characters in a word', use /\w\w?/g or (identically) /\w{1,2}/g, or any
other definition appropriate for your data.
Not messy at all, eh?

This is Perl not a batch file.
Perl doesnt know anything about the %blah% construct that passes for
environment variable handling in the MS world. You will have to actually
have to get the value of the SystemRoot variable from the ENV hash thus:
$SystemRoot = $ENV{'SystemRoot'};
and then put that in your string.

I'm not entirely sure what it is that you want here.
I think that your problem is trying to use substr when it would be far
better to use a regex or split();
alternatively you can use index() to locate the dots in your data and then
use the information thus gleaned to extract using substr().
ie:
#!/usr/bin/perl
$host = 'hostname.mycompany.com';
if ( $host =~ /^(\w+?)\..*/ )
{
$hostname1 = $1;
}
($hostname2,$domain) = split(/\./,$host);
$firstdot = index($host,'.');
$hostname3 = substr($host,0,$firstdot);
print "By regex : $hostname1\n";
print "By split : $hostname2\n";
print "By substr: $hostname3\n";
A quick benchmark on these various methods gives this:
Benchmark: timing 262144 iterations of Regex, Split, Substr...
Regex: 9 wallclock secs ( 9.56 usr + 0.00 sys = 9.56 CPU)
Split: 8 wallclock secs ( 7.83 usr + 0.00 sys = 7.83 CPU)
Substr: 3 wallclock secs ( 4.05 usr + 0.00 sys = 4.05 CPU)
So infact your substr approach is probably the most efficient except
that you were going about it the wrong way.
