Well, my observations of this newgroup have been that Learning Perl et
al. published by O'Reilly are well-respected. Every other book I've seen
mentioned here has been chastised (with good reason).

Great! Care to share what they are with the rest of us?

_Effective Perl Programming_ written by Joseph N. Hall, an
infrequent visitor here, is a very good book. Randal is
featured in this book. It is published by Addison Wesley.
Effective Perl Programming
Hall, Joseph N. with Randal L. Schwartz
1998
Addison Wesley Longman, Inc. Mass.
ISBN 0-201-41975-0
This book is printed on recycled acid free alkaline paper.
* thumbs up *
Although intended for advanced programmers, there is something
to learn for all skill levels. For a technical journalist,
Joseph Hall's writing style is very good, darn good actually.
His convention parameters and introductory documentation are
excellent, significantly better than any ORA books I have.
Hall's book is exceptionally well organized and his indexes
are well done. His book, overall, out-shines any ORA book.
Only reservation I have is I wish Hall would write more books.
Godzilla!

Ooops!
I did leave out one line and that was the subroutine declaration:
Here, totally double-checked, is the code in the book (line 4 below is what
I left out):
1 #!/usr/bin/perl
2
3 print DisplayMessage("Please wait..", 4);
4 sub DisplayMessage
5 {
6 for ($x = 0; $x <= $_[1]; $x++)
7 {
8 $temp = $temp . $_[0] . "\n";
9 }
10 return $temp;
11 }
Next time I'll copy and paste but I'll have to install the CD that
came with the book first.
The book doesn't use -w or strict which I thought was a bit lax
especially for a beginner's Perl text.
I should also apologize for my choice of words . . . I do understand
that the equal sign " = " is an assignment operator, and that $temp . $_[0]
. "\n" was being *assigned* to the variable $temp.
Thank you's to Bart, Joe, Uri, Tad & Michael (sorry if I left someone out),
your explanations, warnings, and recommendations for what to do with this
book I have were great :)

So then you must have missed the articles mentioning:
"Object Oriented Perl" Damian Conway (Manning)
"Elements of Programming with Perl" Andrew Johnson (Manning)
"Effective Perl Programming" Joseph Hall (Addison-Wesley)
"Perl: The Programmer's Companion" Nigel Chapman (John Wiley and Sons)
all also highly regarded.

*sigh* I've got to start paying more attention to publishers. :/
Better yet, I'll give up my budding career as a literary critic.
Thanks for the tip; all have been added to my list of things to check
out the next time I'm at the bookstore.

if you learn nothing else from this thread, that is a good lesson. we
have seen too many newbies who retype code incorrectly and then don't
get why they are flamed for it. code is too precise an entity to allow
typos in.
R> The book doesn't use -w or strict which I thought was a bit lax

very true. a major reason to throw it out. there has been debate on
using them in production code (i am totally in favor of that), but
beginners should always use them.

well, that was never made clear. you were writing as if = was a
comparison operator.

The astute reader will note how short the list of acceptable
non-O'Reilly Perl books is (I'm sure I've missed a few).
So your claim was acceptable within a reasonable amount of variance :-)

What is your Perl question?

So, this is a Windows NT dile/directory permissions question and has
precisely _nothing_ to do with Perl. Using an appropriate NG is sopmething
to consider for your next question.
Nevertheless, IIS runs by default with an effective user name of
IUSR_computername and it is this user that needs permission. See the
section of the IIS manual covering Securing Your IIS Server.

What would I do in the webpage/script to make the make the server recognize
that the script has the privileges to write to a directory which cannot
otherwise be written to by ordinary web users. In other words, I am looking
for advice on a user authentication solution that will acquire write
privileges for my perl script. Your question suggests to me that it can
perhaps be accomplished outside the script. Am I right? I am a newbie. Please
bear with the ignorance.

Nothing, hence it is not a Perl question.

Sounds like a web server question. You should ask in a web server
newsgroup such as:
comp.infosystems.www.servers.mac
comp.infosystems.www.servers.misc
comp.infosystems.www.servers.ms-windows
comp.infosystems.www.servers.unix
or maybe in:
comp.infosystems.www.authoring.cgi
>In other words, I am looking

User authentication is handled at the server level, not at the
programming language level. You have a server setup question.
Perl does not _have_ a server, so talking about servers in the
Perl newsgroup is probably not on-topic.
>that will acquire write
>privileges for my perl script. Your question suggests to me that it can

^^^^^^^
Not perhaps. Must.
So you do not have a Perl question.
> I am a newbie. Please
>bear with the ignorance.
Have you tried typing this yet:
perldoc -q CGI
In particular, this Perl Frequently Asked Question
"Where can I learn about CGI or Web programming in Perl?"
might help you to be able to partition the problem more effectively.
