check out perlfunc for the -X stuff
i.e :

or whatever "man perlfunc" then /-X blah blah
Perl has a whole shed-load of ways of finding this kind of stuff out.

Your problem might be the wrap="virtual"
this gives the person entering data in the form a word wrap but the
data comming to the perl script does not wrap.
Are you pressing "enter" after each line?
have you tried pressing "enter" twice after each line to give a line
break between?
You might also try changing your wrap to pshyical as see that that
gives you what you want.

There are plenty of good editors out there, some of which might make a
fair fist of syntax highlighting but as far as I know there are none
that will be able to provide assistance in that manner although it
might be possible with some of the more configurable editors available
to write a macro to do that.

That is not strictly correct in both case: Visual C++ *is* a C++ that
*happens* to largely depend on a monolithic proprietary class library
and an over clever IDE, so yes one could treat it as an ordinary C++
as far as the available libraries would allow. However Visual Basic
merely employs a BASIC-like syntax : BASIC per-se does not have
objects, classes, or event handlers: the design of BASIC does not
allow for a framework to take responsibilty for the flow of control as
it can in C++ - This is the reason, as I see it, why Borland did not
call Delphi Visual Pascal or something similar. The snip of code you
cite above is not valid BASIC code - but its moral equivalent from
Visual C++ would be valid C++ given the correct class libraries.

I corrected the syntax stuff I think--at least I I don't think this sounds
like a syntax error:

(that's the error)
Is there a list somewhere of errors and what they mean exactly?

Why not just link to AltaVista or one of the other search engines
which will allow you to use a linkback to your site? That should be
sufficient for a personal web page.
If this is for something bigger or more commercial (where you want
to look like you're doing everything yourself) then you need to get
a different ISP.
BTW, this didn't really have anything to do with perl, except that
perl is a language you might choose to write CGI scripts in.

My advice is to learn to program in CGI/Perl.
Perl is available for most servers that I know of.
ASP will only work on Microsoft IIS servers without special server
upgrades. You can get chilisoft's chiliASP to run ASP on a netscape
server.
You need to run a cold fusion server to get all the benifits of Cold
fusion and not one of the local ISP's here use it.
If you go with Perl, and your server does not have it you could easily
get it for them for free!
If you want a really good book for learning perl from the ground up I
recommend:
Perl 5 Interactive Course : Certified Edition
by Jon Orwant
Waite Group Press; ISBN: 1571691138
This book is like a college course in perl
it introduces topics slowly and tests you on what you learned after
each chapter.

You're almost certainly right. But nonetheless if gcc2 *is*
executable and in the PATH then the message from the shell indicates
to me that the Interpreter described in the shebang line is incorrect
- this goes for Perl programs giving a similar type of error.

Most usually when Perl claims that some function or other is not
implemented on your platform you can be pretty sure that it is telling
the truth - however if you did not compile Perl yourself and you are
sure that the setgid() C library function is available to you (which
is fairly certain on a SVR4 type system ) then you might want to
rebuild Perl yourself and check that it is doing the right thing.

check out the documentation for the fork and exec builtin functions in
the perlfunc manpage. system() does an implicit fork(),exec(),wait()
but by removing the wait() until the last possible moment before your
programs termination you can run your scripts asynchronously.

I dont know is this Perl, is this CGI, is this Javascript ?
The thing here is you probably dont need to use the javascript to get
the cookie if you do the right thing with CGI.pm but that is probably
better answered by the documentation for that module.
Alternatively, you might feel that you want to use the Javascript
anyway and if this was comp.lang.javascript I would probably give you
an answer but it isnt and I wont. You could probably get an answer
from the Netscape documentation for JavaScript I suppose (and there is
plenty of it.)
As a third option you might check out the HTTP and CGI specifications
and see how the whole matter of cookies is dealt with.

My preference is elvis, I used before it was able to do keyword
highlighting but now it does and I wouldnt use any thing else. Of
course its a vi, it dont have a gui - but those are plus points really
arent they ? You might want to think about the difference between
syntax higlighting and the syntax checking that you seem to want. It
is an oft stated truism that the only thing that can check Perl syntax

Subject: Perl to Browser IO problem
Message-Id: <359E8FFA.49E10DA4@home.com>
Hello, and thanks for the help in advance;
I've installed perl on my Windows95 machine, and I'm having difficulty
getting my browsers to execute a script. Specifically, the contents of
this script fail to dump into the browser window. Instead, it opens a
DOS window and dumps there.
Below is a perl script called "a.pl":
-----------------------------------------------------------------
#!/perl/bin/perl
print ("Content-type: text/html\n\n");
print("<HTML>\n");
print("<HEAD><TITLE>Here is the title</TITLE></HEAD>\n");
print("<BODY><P>Here is the body</BODY>\n");
print("</HTML>\n");
exit (0);
-----------------------------------------------------------------
If I use a browser to run it ("c:/temp/a.pl"); the browser starts a
"file download" and asks me if I would like to open it or save it to
disk. I click on "Open it", at which point a DOS window opens, the
script executes, and dumps its contents into this DOS widow, but NOT
into the browser widow.
How do I get this script to print into the browser window?
I assumed that the IO automatically redirected into the browser if the
browser called it, but that does not seem to be the case.
Below is my system configuration:
system: Windows95 (4.00.950a)
perl version: perl 5.003_07
perl download:
ftp://ftp.activestate.com/Perl-Win32/Release/Pw32i316.exe
browsers: Internet Explorer 3.02
browsers: Netscape Communicator 4.02
I've associated the ".pl" extension with perl.exe through the widows
"registered file types" so Windows95 will execute all files with the
".pl" as perl scripts. (Note: this association does NOT work in a DOS
window.)
If I run this script in a DOS window (e.g. "perl a.pl"), it prints HTML
contents to the screen with no problems.
If I run this script through Windows95 Explorer (double click on
"a.pl"), it opens a DOS window and prints HTML contents to it with no
problems.
thanks for the help;

But you just cant go doing CGI without an HTTP server now can you ?
This question gets asked here quite a lot but it hasnt made the Perl
FAQ because it has nothing to with Perl. The way that you describe
that you are running your scripts and the results you get are entirely
consistent. YOU NEED AN HTTP SERVER TO DO CGI. This has been
discussed here before - search DejaNews or ask in an appropriate
comp.infosystems.www.servers.* group to your platform (or even better
its FAQ ) about installing and configuring an HTTP server. There even
servers written in Perl but I think you probably want to look at a
more conventional server before you start playing with that kind of
stuff.

If you look through CPAN (www.cpan.org) you'll find a module that works
with Mysql quite nicely; there are also modules for many other databases.
There are also modules that make it a lot easier to deal with data in text
files, but for many applications a database is your best choice.

It depends. Perl will use whatever sorts of threads your OS provides. If

Subject: print $ENV{'PATH_INFO'} problem
Message-Id: <359ea4f7.0@hebel.rol3.com>
Hello,
the following perl code (under SuSE Linux 5.1/2.0.32 perl 5.004 apache 1.2.6
gcc 2.7.2.1) does not produce output as wanted (but a similar code prooves
that it normally does):
----
# script "new-category"
require "config";
print "$Html_AddCategory\n\n</center>\n\n";
# config file "config"
$Html_AddCategory = "<form
action=\"/ext-cgi/add-category$ENV{'THIS_PATH'}\" method=\"GET\">\n <input
type=\"text\" size=\"38\" name=\"name\"><br>\n <input type=\"checkbox\"
name=\"view\"> disable<p>\n <input type=\"SUBMIT\" value=\"Create
Category\">\n</form>";
---
The problem is that the expression $ENV{'PATH_INFO'} is just replaced by a
zero length string (""). When adding it to the print function itself (not
indirectly by adding it to the variable in the config file), it prints the
real PATH_INFO.
It seems to me that perl is somewhat instable at this point. Or is there
something to be beware of?
Thank you, Mark

I've gotta say that you havent got an $ENV{PATH_INFO} in that at all.
That said and assuming that its omission from your file is merely a
typo - you would still be better off if you used CGI.pm and its
path_info() method.

Way to go Ron ! And I thought I had an unfortunate memory.
The thing we have here is that there are people out there who might be
able to demonstrate a reasonable degree of proficiency as creators of
little Perl scripts within a relatively controlled or convivial
environment and might be able to convince some of their peers or
superiors of that - of course sometime they might fail but hey !
There is no substitute for programming experience or experience of
working through the whole product life cycle - Perl is a relatively
easy language for someone of reasonable intelligence to become
apparently productive in without ever having the need to become highly
skilled as a professional developer of software.
It is probably too easy to go barrel fish shooting around here, I have
to confess that Perl is only a minor ranking skill on my CV - I was
employed initially with my current employers as an Informix/Unix
product specialist, but so many files have been frigged, so may
reports fixed up, so many data conversions, interfaces, transfers and
so on and so forth in Perl that it is my de facto choice for any job
that it is capable to do - (and we all know there are things you wont
do in Perl.)
Anyhow. David Beckham walks into the Sperm bank and says he wants to
make a donation. The nurse asks him whether he has donated before to
which he answers positively. "Ok I'll just look on the computer for
your details" she says. After a short while she looks up and says :
"I'm sorry Mister Beckham but you'll have to wait until we can get
Posh Spice here before you can make your donation". "Why's that?", he
say's. "Well it says on your file you're a Useless wanker ..."
;-}
Thats the end of football for now.

Where did you hear that?
It's true under Unix, but editors that run under Unix don't put
carriage returns in the file unless you intentionally do it (in the
editors I'm aware of, it's very hard to do this accidently).
Under Windows 32 scripts, like any other text files, should terminate
lines with a carriage return/line feed. This will cause no problem
for perl.
If I recall correctly, on the Macintosh text file lines normally end
with a carriage return only.
When you transfer a script from one platform to another, you should
convert to the proper text format for that platform. Even if Perl
doesn't care, you'll be happier if the native tools work with your
scripts. When using FTP, just transfer using text mode. unzip, at
least for Unix and Win32, has an option to convert files when it
extracts them from the archive. If nothing else, it's generally
pretty easy to write a perl script that will do the conversion.

Now you won't do this again having seen how horrible it looks to
everyone else now will you? Usenet has no use for this stuff and all
but the most lame newsreaders/browsers even attempt to use it (except
for a saintly few which just wipe it out). Check out the
documentation for your browser if you are unsure how to prevent it
from doing this.

No. You have been advised incorrectly. A Perl interpreter for a
given platform will correctly understand the line end convention for
that platform. However the text format may not be portable between
varying platforms - say between DOS and Unix. If you are transferring
Perl files between two platforms with FTP you want to be sure that you
use ASCII mode in order that the software perfroms the correct
translations for line end characters. If you are using some other
method of transferring files (such as samba or NFS) then you might
want to look at an editor that will let you save in the appropriate
format such as PFE (Programmers File Editor) or SuperNoteTab on the
windows platform.

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
