I think he might be messing with browser plugins/MIME-types.
The only reason I say this, is that I wrote an application to be kicked off by my
browser when I hit certain files.
In my Netscape preferences, under Navigation->applications, I've defined a MIME-type and
associated application. The application has a command-line of:
/path/to/script %s
%s is normally the path to a temp dir (IIRC). I can't recall if that is a MIME thing or
a Netscape thing.
At least that's my best guess.

Are you by any chance a MS Windows user? The %0 %1 etc. look like
the way it denotes parameters in scripting.
If so, the "%0 %1 %2" in "perl -S %0 %1 %2" is nothing to do with
perl, but rather it is to do with the scripting language that this
particular line was written in.

They are, in DOS batch files. But the actual syntax is usually as follows :
perl -x -S "%0" %1 %2 %3 %4 %5 %6 %7 %8 %9
or for Windows NT :
perl -x -S "%0" %*
%0 represents the command itself, and %1..%9 are the command line
arguments.
Have a look at the pl2bat.bat file in your ...\Perl\bin directory, for
instance.
Have fun,

Hello.
I just started study PERL and I have few scripts that I wrote in AWK.
I found the utility a2p that supposed to convert awk script to perl script
with same functionality, but somehow I didn't manage to make it work.
What I did is the following:
issue the "a2p my_script.awk" command from my tcsh console, it seems that
command is completed (without producing any output) and exit status is "1".
Any ideas?

There is more than one approach here. You could save the results
of entire search in a temp file and then read next 20 from this file.
The 'NEXT 20' URL contain information to read from this file.
However, this is a good approach if the number of results is manageable.
Databases like Oracle have a pseudo column like rownum that
numbers your rows so that you can say --
select whatever from table where rownum > x and rownum < y.
You could use such a facility if it is provided.
Lastly, you can resort to some ordering mechanism on a column
to make this possible. For example if you are currently displaying
employees with employee id upto 200 the next 20 records
should have employee id > 200.
> Do I create some kind of reference to an aray or something?
No. You cannot do this because once the page is displayed
the script exits.

That's a bad idea. Access doesn't scale well at all, it isn't designed
for access by multiple users at once, and its mother dresses it funny.
Get a real database. Even if you must use Windows, there are plenty of
databases, some free, that you can use instead of Access.

Look at DBI. It lets you access any number of databases (assuming you
have the right DBD (database driver)) from perl. It's well-documented
("perldoc DBI"), and easy to use-- I figured it out from the
documentation and had a simple program running in about 10 minutes after
installing my DBD driver. See CPAN for the right DBD driver for your
database.

The page you are referring to is a dynamically generated page.
I am saying this because If you try to follow http://www.food.com/index.html
you will not find this index.html page.
Each time the serverside program/script that is responsible for creating
this page is invoked it generates this page with a different image
tucked in each time. No special cgi scripts are needed. If the
image had been displayed earlier then it will be loaded from
the cache -- no harm done.
The other technique you could use is having a image tag ( that
will differ every time ) like
<img src=/cgi-bin/imagegenerator?random=12232 border=0>
with a different value for random each time. Names of gif
files are never displayed. The imagegenerator then dumps
the image file randomizing the display using the random value
passed to it using some simple algorithm.
The imagegenrator script could be something like this ( in pseudo code..)
read the random value ;
choose the GIF file to display;
open gif file and read it entirely
print "image/gif\n\n"
print entire contents of gif file
exit ;
Hope this helps..

Oh, now you're only gonna follow the rules you signed. Does that apply
everywhere, or just in arguments you can't win? Like you never signed
the Constitution, the Geneva conventions, the golden rule, the ten
commandments, gravity... It's all just opinion, and you never signed it

Here are some sources that reinforce what I said:
FYI28/RFC1855. There's the "Rules for posting to Usenet" article that
appears in *.answers . If you speak satire, there's the classic "Emily
Postnews" article. There's the Usenet guide at LSU, or another at the
University of Alberta, or another at the University of Cincinnati,
etcetera.
Over and over, I see this line:
Reply to other people's articles by mail unless there is a specific
reason to do otherwise.
Now, -please- tell me what source you've seen which contradicts that.
Or tell me it's your opinion, and others might have a different one.

You give me too much credit. All I did was agree that what you're
saying -is- an opinion. I wouldn't argue with your opinion if you
wanted to say you had one, but once you try to tell me it's the rule, I
want to ask why.

No, here comes that gray area.

If active usenauts are no longer able to discern the difference between
Usenet replies that use the email channel and UCE, then the spammers
have won by obscuration. I'll worry when the net abuse admins lose that
distinction. You might want to ask them what they think, if you're
still on speaking terms with any of them.

When strings get interpreted as numbers they are constructed by reading
digits one at a time from the beginning of the string stopping when a
non-digit is encountered. So "a" will be 0 when interpreted as a
number. Your results are as expected.

Fortunately for you, this very question is answered in perlfaq7: "What is
variable suicide and how can I prevent it?"
There's another FAQ that answers the question about dynamic scoping
issues in the same manpage (perlfaq7): "What's the difference between
dynamic and lexical (static) scoping? Between local() and my()?"
> Is it a good practice to use "use strict"
Always. I use it in all my production Perl code, and I can honestly say
that it has made me a better Perl programmer. I'm only half-joking when
I say that the BUGS section of the perl manpage should also say
"use strict is not mandatory."

This is directly from the perl faq (8).
You can also do this for most systems using the Term::ReadKey module from
CPAN, which is easier to use and in theory more portable.
use Term::ReadKey;
ReadMode('noecho');
$password = ReadLine(0);

You need to lock the file and seek to the end before attempting

I'm currently writing a large system that needs to be

multiple scripts, modules, config files and documentation.
All of this is being managed directly through cvs.
If anyone has pointers as to how the perl sources
are managed and packaged together for release I would really
like to hear about it.
I've been using h2xs for setting up the perl modules, but I think
I need something a little different to manage the entire release.
It looks like a custom Release/Build Management tool may be in my
future so if anyone has tips for binding cvs and perl, they could
come in handy.

What editors are folks using for PerlScript development under Windows? I
have had some success with Homesite but would like to use Visual Interdev.
Is there anyway to get Interdev to parse Perl? Is there a better editor I
should use instead?

Allright, let's assume a peak hour of 2M (why not), so we'll have
about 556 updates/appends per second. That's not bad at all.
So you may not want to do an exclusive locking on the whole
file, but only on the relevant part(s) to be updated/appended, maybe ?
So if flock() is not for you, maybe you could try fcntl().
Oh, but what systems are you going to run this thing on ?
Do they support flock, fcntl, lockf, ... ?
And how big a file are we talking about ?

Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq" from
almanac@ruby.oce.orst.edu. The real FAQ, as it appeared last in the
newsgroup, can be retrieved with the request "send perl-users FAQ" from
almanac@ruby.oce.orst.edu. Due to their sizes, neither the Meta-FAQ nor
the FAQ are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq" from
almanac@ruby.oce.orst.edu.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
