I write scripts that I test under NT (with ActiveState) and that run
unchanged under UNIX. These incorporate both standard modules and
personal ones.
Screen.pm doesn't appear to be part of the standard NT distribution. In
what directory did you put that file (I keep my personal ones in
\perl\site\lib and they get found automatically by Perl.) What is line
37 of Screen.pm?

Like I say in my book, "Web *browsers* are incapable of running CGI
programs. Only a web *server* can do the job." (p. 140)
I particularly like my euphamistic choice of words for bloatware, too,
"marvelously feature rich", when describing web browsers :) I don't
flat out say they're loaded so that they can hardly go, but you can read
between the lines. :)

If you want to go with all-Microsoft technologies anyway, you might as
well use ASP too, since it is a tremendous timesaver. But don't expect to
port it anywhere, and be warned that NT has certain reliability problems
(called the "blue screen of death). Use ASP and PerlScript, and you'll
be in good shape.

In this case you'll have to include links (i.e.
<A HREF="PathToYourScript">Execute Script!</A>)
If you're new to CGI you might want to read

This can be done by sending a redirect (i.e. let your script
end with:
my $Url = "http://this.is.your/old/page/foo/bar/something.html";
print "Location: http://$Url\n";
print "URI: http://$Url\n\n";
If I wasn't specific enough on some point, don't hesitate to ask again.

it is not possible, you cannot access a 'my' variable inside a sub
#!/usr/bin/perl
sub x { $_=shift; print "\$$_ = ${$_}\n"}
$a = "hallo"; {my $a="peter"; x 'a'; print "\$a = $a\n"}
=cut
$a = hallo
$a = peter
for non-my variables, possible names can be found with a reference by
searching all symbol tables, but what for?
use Data::Dumper;
print "\$a is ". Dumper($a);

I have a problem with a perl program that fails

small script is attached that has this same
problem. Wether or not the 'undef' line is
commented out, in both cases the script fails.
I have checked the FAQ, but could find only one

Does anyone have a fix or a workaround for me?

Because shift is an inplace modifier of arrays and what split returns is a
immutable list value?
But why is it not possible to get all but the first element from a list
value? Something like the "cdr", "butfirst", "next" functions, or the [1:]
idexing notation available in some other languages.

Isn't the real issue why it is still a list value and not an array value
after assignment to an array:
shift(@array = split)
Why does this not simply shift @array? Is this a DWIM failure?

Thanks for the response. Unfortunately, your email address doesn't seem

Anyways, that seemed to work, but I've got another question for you. Some
of our users here have a filter-id on the next line under their username,
how would I modify this to also delete the filter-id line if it exists.
Thanks again for the assistance, I really appreciate it!

In general that should be good advice, although of course _only_ in
situations where a posting really belongs on more than one group. Unlike
this one, which doesn't belong on EITHER of these groups, because it's
answered by BOTH of their FAQs.
But c.i.w.authoring.cgi is automoderated, and prohibits crossposting,
precisely because postings that belong there should not be posted to
irrelevant groups like, for instance, clpm. All properly behaved
posters to ciwac get an email explaining this to them before their first
posting is actioned. I wonder whether any of them read it?

Actually, if you looked at the perl in the posting you might think it
should have just been posted here in c.l.p.m ;)

Oh, I thought I'd seen crossposted articles. Maybe that's why people
complain that their messages don't make it in???

Why doesn't that email hide some token in the faq and say "Find the
magic key to gain access...." -- Why that could work here in c.l.p.m.
Send the entire perlfaq by email with bits of the 'key' hidden through

Hi all,
I've go a variable containing stuff like brackets, *s, ?s, etc.

I would now like to do a "substring-compare":

if ( $HugeExpr =~ /'$Expr'/ ) {

} else {
print "no luck\n";
}
I guess you get what I mean to do; Perl doesn't. Do I have to substitute

there an easier way?

You're still not checking for success on your "open"s and "flock"s.
Also, because of the "if (-e $pagepath)", you now have a race condition if
the file doesn't exist.
Depending on your needs, you may be able to get away with opening the file
as 'open (INF, "+>>$pagepath")' -- this is "read/append" mode which will
create the file if it doesn't exist already. I believe the only downside
to this approach is that you can only write to the end of the file in
question, meaning that you'll have to truncate it (perldoc -f trunc) after
reading it if you want to write to the beginning.

Unless you can do a SELECT on the row sequence number on the table,
you will probably need a cursor to do this. Some databases have a field
for each table that generates a unique sequence number for each row,
which I think is accessible to the user for reading but not modifying
in some databases.
Relational databases are *NOT* designed to do this, however, and I have
to wonder about the design of a solution that uses this particular type
of record selection. Rows are not kept "in order" in a relational
database.

You have to backwhack it in a regular expression, because
| itself is a regular expression character. If you don't,
Perl will be trying to match two empty regular expressions :)

Use CGI.
Usenet is not the place to start. Search the web for CGI tutorials and
FAQs.
And look at:
perldoc CGI
And, please read the FAQs.

Subject: tool to convert BMPs to GIFs programatically?
Message-Id: <rvk62rh1rad28@corp.supernews.com>
I want to convert some BMPs to GIFs using code, without any user
interaction.
Is there a utility that is scriptable, or batchable, or supports automation
to do this?
Ideally it would be freeware and re-distributable...
Thank you,
- Colin Reinhardt

Check out Image::Magick. You will need to install ImageMagick to use
it, though. ImageMagick can be found at
http://www.wizards.dupont.com/cristy/ImageMagick.
followups set.

Unfortunately, this is not possible since Unisys enforces a strict
licensing-policy on their GIF-patent.

But GIFs are patent-protected, or something, and require a license
from whoever has the legal rights to them, aren't they? Can you
make freeware that supports GIFs without having to pay
for the rights to them?
