If you choose the "standard distribution" version, (not the ActiveState version)
you will find a bunch of Tk related stuff included. I haven't worked with it on
Win32, but there are some running demos included that put a GUI on top of Win32
Perl.

I'd be willing to bet that you do it every day. Do you ever refer to
"the sun rising"? Does it really? A "blue sky"? Tell me, where is
this blue that is inherent in the sky?
Y'know, Chris, ultimately it's all simplifying fictions. What's
ultimate reality? Quarks? Strings? You yourself are almost entirely
"empty" space. If you "touch" something, no particle making up your
body actually "touches" another. We're dealing with the repulsive force
between the electron clouds surrounding the nuclei of the atoms of the
things "touching".

Good point, actually. The closer analogy, rather than to unicellular
creatures, would be to viri, which don't really do anything without the
aid of the host. In fact, "sits in a leather binding" reminds me a lot
of viri in their protein coats...
Of course, viri are said to "evolve", implying they are doing something,
rather than being passively selected, which would seem to be the real
case. It's just a shorthand to help us human beings think easily about
what's going on. We think more easily in terms of beings with wills,
"driving force", what have you. Simplifying fictions, again.
(I think talking about software "wanting to be free" is at least
defensible as such a simplifying fiction, but may not work for some).
It was common practice at a company I worked for to refer to programs as
"he". Made it easier to visualize the interactions. ("At that point,
he wants a keystroke from the user.") It just made it that tiny bit
easier to "get inside" the program, by identification. (Try it some day
in your conversations about some sort of program interaction, as a
thought experiment). Did we think the programs actually had gender or
will? *Not*.

Well, I would argue that thise are true, based on our senses.

You make a very good point. I have no problem with saying something that
is not true for simplicity's sake so long as we all know it is not true.
But in this case, many people think that information actually does will
and act.
# (I think talking about software "wanting to be free" is at least

I agree. I am just guarding against the notions that information in
actuality desires something, or does something, anything, at all.
Thanks for your post.

If people are told "this is a CGI question, this is not a CGI group"
and are uncapable of grepping for cgi in their list of newsgroups,
I don't give them much hope that any answer will satisfy them.
I assume people looking for the frozen food section know they can find
that in a supermarket, they mistake the library for a supermarket.
Apperently, you don't give them that credit.
BTW, if you don't like my answers, ignore them.

I can think of three or four things that this *might* mean, and on the
other hand it might not mean any of those things. Without knowing
what program is printing this message, it is impossible to begin
investigating this problem. A program might print `error number 8'
unter any circumstances at all, depending on the program.
Is this message coming from Perl itself? Or is it being printed by
your Perl script? Or by some other program?

That's not a perl language question. You would need to review DNS

You can't reliably verify email addresses. That isn't a perl language
question either, but in spite of that, it's asked so often that the perl
FAQ contains an entry explaining why ("perldoc perlfaq" tells me that
it's in FAQ part 9. And indeed "perldoc perlfaq9" contains an entry
"How do I check a valid email address?", the answer "you can't", and a
lot of instructive discussion.

And some servers will say yes to every question. And some will refuse

:Is perl 5.004_64 slower???
Yes, it is. I am using perl 5.004_64 on a SPARC 4 with lots of memory,
Sun's compiler with lots of optimization at compile time.
When I ran the script above using an old version of perl (5.004_01) I got
times of 3.82/2.16/0.50, 2.64/2.17/0.35, 2.62/2.16/0.37 using the time
command.
Then, using perl 5.004_64 gives me times of 8.28/5.29/0.40, 5.81/5.29/0.30,
and 5.72/5.27/0.36 .
Looks like the system times are in the same ball park, but user time is
about twice as slow. Note this has _nothing_ to do with threading compiled
in - I wasn't able to get the threading code to compile in my environment
the last time I tried.

Subject: Perl writes to DOS window instead of browser
Message-Id: <01bd6774$56d04940$aa032399@cu-dialup.cornell.edu>
Hi,
I am using PERL 5.003 on Windows 95 using Personal Web Server (IIS) and IE
3.02.
I am beginning to learn PERL and CGI (as may be obvious). I have set up a
simple PERL script from Sol and Birznieks book which outputs HTML. I access
the script from a link on a standard HTML page. The script executes,
however it outputs to the DOS window instead of to my browser. Can anyone
tell me what is happening here and how to get the PERL script to output to
the browser instead?
Thanks.
Richard

Thanks for the correction. I'm really glad to learn that I was
mistaken about this.
I wasn't able to find the information I wanted on the site, but I
think that's because their site is broken, and not because they
weren't willing to divulge it.

Unless I'm missing something, you don't need perl to do this. Just
scan the document into WORD, then save it as a template.
If you need to reformat it, you can use a WORD macro to do so and then
save it for you.

Subject: Returning an array from an XS routine?
Message-Id: <35337444.674BC10@nada.kth.se>
Hello all,
I am trying to write a Perl extension that features an XS function
that will return a list (or is that an array? This perlminology always
gets me confused). There are some functions that I call to obtain
elements of the list. Basically, what I have looks like this:
void
shown( )
PREINIT:
int n, done;
Layer *layer;
PPCODE:
for ( n = 0, done = 0; ! done; n++ )
{
if ( ( layer = Layer_Get( n ) ) )
{
EXTEND( sp, 1 );
PUSHs( sv_newmortal( ) );
printf( "A layer at 0x%p.\n", layer );
sv_setref_pv( ST( 0 ), "LayerPtr", ( void* )layer );
Layer_Ref( layer );
}
else
done = 1;
}
Layer_Get is the function that returns the nth element of a list (yes, I
know this is inefficient, but that's not the point). Layer_Ref keeps
track of the reference count of the Layer.
What's wrong with this function? The print statement prints two layers
(which seems correct), but the return value of the function only
contains one element.
Grateful for help,
Johannes.

I can see where the docs are unclear: It says, explicitly, in the
quoted passage, that list context can be propagated to the right
operand, implying that the left operand is sometimes evaluated in list
context. We'd benefit from a clarification, if you (rootbeer) or one
of the other gurus would care to step in.

As I was shepherding the new Camel through the final months of writing
(as lead writer), I had to make some tradeoffs given the limited
resources we had. We didn't have the writing or editing staff to do
both the module library doc *and* update the Real Programs section.
So, I leaned towards the module docs.
Some have argued with my decision, but it's the way I called it.
In an ideal world, we would have done both.
Same thing for the "Common Tasks"... it fell below the resource
cutline. *That* section is seeing the light of day in a forthcoming
book, though. (I hope I'm not revealing too much there... :-)
(Besides, I couldn't rightly put out another Perl book that used
the "g___" operator... :-)
Digital> Are these examples in the new "Learning Perl" book?
No. The llama/gecko has its own examples, but very few complete
practical programs (unless you look at the exercise answers).
Digital> If not, are they online somewhere?
Those examples, and *thousands* more, are found all over the Net. :-)

Subject: Re: Which Win32 Perl
Message-Id: <gerlachErEu8w.DH9@netcom.com>
In addition to the two versions you mention, there is DJGPP port of perl,
www.delorie.com/djgpp/. DJGPP is 32 bit dos protected mode port
of GCC and most of the other gnu tools. Recently, I noticed someone built
perl5.004 using the djgpp.
Like all the DJGPP tools, the perl port supports looooooong command lines.
This has been of particular interest to me since I use a few perl scripts
in my software compile process. My makedepend perl script, like the X11 tool,
benefits from long command lines due to cacheing of dependencies.
Since its built with djgpp's gcc, and appears to have all the stuff for
making modules, I imagine it would be a nice evironment to glue C code
into perl.
