Hello to all.
In Unix "$?" will return 0 if the job is done and success.
My Perl script in Unix can regconize that too.
What about NT???
Seems that my "$?" always return 0 even though the job is fail.
Any help will be very appreciated.

Thanks for the quick reply! I actually just subscribed and sent an
announcement out! As usual I should have done more digging before I
asked! Now everyone else will know the list is there.
Is there an archive for people who are reading this? It seems like for
something like this, a week or three's worth of posts would be
sufficient and very helpful. What do you think?
Thanks!

Message-Id: <3755fe5e.0@206.103.97.91>
The SELECT form tags need special handling, because you can't just use a
VALUE="$field_name"
I realize that you're using genders, but here's the script that I use to run
through the 50 US states that remembers the state the user chose by adding
the SELECTED in the line the user chose. You can adapt it to suit your
needs.
#First, toss the states into an array
@us_states = (
'Alabama',
'More States Here',
'Wyoming'
);
# Start defining the drop down menu
$state_drop_down = qq~
<SELECT NAME="state">
<OPTION VALUE=""> Please select your State</OPTION>
~;
# Run through each state, put a SELECTED
# next to user input
foreach $item(@us_states) {
if ($state eq $item){
$state_drop_down .= " <OPTION VALUE=\"$item\"
SELECTED>$item</OPTION>\n";
}
else {
$state_drop_down .= " <OPTION
VALUE=\"$item\">$item</OPTION>\n";
}
}
# Finished running through states, close drop down menu.
$state_drop_down .= "</SELECT>\n";
# Print it
print "$state_drop_down";
I'm sure it can be perfected, but it it does the job.
Hope this helps,

I need to distribute Perl programs to Windows machines that don't have
Perl installed. I have the latest Win32 port of Perl that comes with a
compiler facility: perlcc. Unfortunately it doesn't work. In a
programming forum they direct me to this group believing that there is a
patch available for this problem. If any one knows where can I get it I
would be very thankful. I like Perl and I want to use it but if I can't
distribute my programs to non Perl computers I'll be forced to use
another language.

So, what's' the problem? Is your NT system not running the scripts? Is
it not recognizing them as Perl scripts, or associating them with the
Perl executable? Is it error-ing? Is it showing your scripts as if they
were a text file in your web browser? What? Depending on your answer
(and by the looks of the code you posted) it may very well be a question
better posted in a web server NG.

XML::Parser is what's returning the error - it's not hosed, some XML
file that it's trying to parse is hosed. Either all the ppd's on AS's

Look around for "tinyweb" (www.tucows.com), it's a small tsr that enables you to

it's free :-)

Yes, on your machine you will have the .pl extension associated with
your perl.exe in the file type dialog.
I have .pl associated with wordpad for editing reasons.
to run in dos you must then type >perl script.pl to run it.
To change your assoc's in a File window,
View->Options->FileTypes
Look for perl file or PL file and select edit and change the exe to one
you want.

if you have that many files in a single dir, it doesn't matter what you
do with the files. the open will kill you as in most file systems that
is a linear search for the file name in the dir.
and you first mention 100+ Million files and then 1 million? which do

You probably mean "not many *Unix* file systems". For me it is
obvious that the guy in question is not using something as restricted
as this.
But the digit 100,000,000+ indeed looks suspicious. This is probably
not a PC - even with HPFS386 you need at least two blocks for a
non-empty file, which gives 1K per file, and means 100G. This rules
out anything PCish. But AFAIK HPFS386 has no problem with directories
with several millions of files. I did never check it, I'm running
OS/2 client, not server, and it has only HPFS, which is much worse -
its performance was reported to decrease starting from circa 200000
files in a directory.
Probably a mainframe...

any you mention 1 filesystem that can handle that. maybe a couple of
mainframe ones could too. that means most/not many others could
regardless of whether they are unix.
and given the unclear nature of the post, presuming what he meant
requires the PSI::ESP module. i would hope he read the replies and posts
a better question with some real specifics. and he should make it more
perl specific. these file system ideas are not perlish issues. any
program would clog opening that many files unless the file system was
designed to handle it. i had first hand experience many years ago with a
single dir having hourly log files. it got pretty bad until i rewrote it
to do daily logs in a dir tree.

I only asked a simple (for you guys) question. There is no need for
sarcasm or for you to put me down in any way like this. You could
simply have said "hey, and if you want more information I suggest you
read the xxxx man page". I mean, God damn it! Not everyone works in a
bloody computer lab and tinkers with linux all the time for a hobby,
ok? Not everyone knows what man pages to look in for what information.
I mean, forgive me for not seeing the obvious here, but I always thought
these newsgroups were to help people out, ask questions to the
knowledgable and to find out answers and, hopefully, learn from what
you've been told. Not to have your abilities, or lack thereof, be put
down with mindless sarcasm all because someone's been better trained, or
has more experience than someone else. For Christ's sake, we all have
to start off somewhere and it's makes it hell of a lot sodding easier
when you get HELPFUL comments and not sarcastic ones.
But other than that, thank you for your answer :) And thank you to
those others as well that have answered it and helped me out. I know
now a URL I can look up for help on regex, and I also know now to look
into that whole m[] bit.

that's all i get back from my majorly simple perl program
i 'initialize' the scalars with :
$prijslijst_ap=$forms{"prijslijst_ap"};
$prijslijst_dell=$forms{"prijslijst_dell"};
$prijslijst_hp=$forms{"prijslijst_hp"};
$prijslijst_fp=$forms{"prijslijst_fp"};
and then i use them with :
if ($prijslijst_ap ne "") {print "Ik wil een prijslijst van Account
Plus\n";}
if ($prijslijst_dell ne "") {print "Ik wil een prijslijst van Dell\n";}
if ($prijslijst_hp ne "") {print "Ik wil een prijslijst van Hewlett
Packard\n";}
if ($prijslijst_fp ne "") {print "Ik wil een prijslijst van F-Prot\n";}
but then i get the errors you see at the top ..
does anyone have an idea what i'm doing wrong?
i'm gone.. going to get some coke :)

You are using an undefined value....
You shouldn't be testing with 'ne' you should be using a function to
test if the value is defined. I can't tell you about the function since
your next post specifically asked me not to tell you to look up
the documentation and that is where the function you want it documented...

You are bordering on ridiculous if you think you need to support your
premises. Such an argument is an infinite regression.

]It is possible to subscribe to comp.lang.perl.moderated as a mailing list.
]To do so, send mail to majordomo@eyrie.org with "subscribe clpm" in the
]body. Majordomo will then send you instructions on how to confirm your
]subscription. This is provided as a general service for those people who
]cannot receive the newsgroup for whatever reason or who just prefer to
]receive messages via e-mail.
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". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". 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". It appears twice
weekly in the group, but is not distributed in the digest.
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.
