Not missing anything about disabling warnings at runtime, but you forgot
to indent your block's contents. :-)
The 'used only once' message is a compile-time warning. You can't disable
it by turning off warnings at runtime. Not your fault; you were merely
given bad advice.
But those variables _are_ used more than once, if you're using the CGI
module. (You are, aren't you?) That is, once in your code, and additional
times within the module.
So, why are you getting this warning message? My guess is that you aren't
using a recent version of the CGI module. You may have a more recent one
on your machine, but the one you're getting inside your program is either
old or modified. (This is just a guess, but I've been guessing pretty well
lately. :-) Try this program to see which version you really have:
#!/usr/bin/perl -w
use CGI;
print "Content-type: text/plain\n\n";
print "CGI module's version is $CGI::VERSION.\n";
Is it, perhaps, an old version which didn't support those variables?
Hope this helps!

Yes I am using CGI.pm. Version 2.36. How can I find out when
(what version) those variables were added?
I guess if they aren't in my version. Setting them twice only
shuts up -w, but has no effect on the program whatsoever, at
least until they upgrade the server.
This server is in bad need of upgrading for everything, but all
the upgrades are on hold. They are waiting for the new release
of Solaris before completing the upgrades.

They were added sometime after 2.36, from the looks of things. :-)
But you don't have to wait for someone else to install the module; have
you seen the instructions on keeping your own module directory? They're in
the FAQ. Cheers!

Well, I tried to do my best. Sorry. Backtrack is not easy to
understand but it is worst trying to explain it and moreover
when you are not English native speaker.

It helped a lot ¡¡
But now I have to review all my backtracking concepts.
:-((
Would it work the same way when Regex
m{([^/] | [^x]/)*}
trying to match string
'a b x//c /x e x/' ?
I ask because my Perl test gave a match at 'a b x//c ' but,
if I try to explain it in your way it matches until the last
'x' in the string.
Explaining in your way:
The pattern with comments:
m{
(
[^/] # a character other than slash (alt.1)
| # or
[^x]/ # a character other than x, followed by a slash (alt.2)
)* # zero or more
The string broken into pieces used by the RE engine in ¨my brain"
(I am not sure mine is perl compatible yet).
'a' ' ' 'b' 'x' # some non-slashes characters (alt.1)
'//' # a non-x followed by a slash (alt.2)
'c' # another non-slash character (alt.1)
' /' # a non-x followed by a slash (alt.2)
'x' ' ' 'e' ' ' 'x' # more non-slash characters (alt.1)
'/' # both alternative failed, so it will stop
# and will match at previous 'x'.

Unfortunately there is no binary of DBD::Informix available as far as I
know. You will need to compile it yourself : If you have a supported
C compiler and the Informix Client SDK. Of course if you have a
different compiler to the one used by ActiveState to compile their
distribution of Perl you will need to compile Perl yourself as well.

Dont do that. If all else fails you can use DBD::ODBC and the ODBC
drivers that come with the Client SDK. You might want to ask in
comp.databases.informix about other options.

But of course supplied with the knowledge that the manpage will provide
he will be able to write such a thing for himself. If he didnt want to
write a program he wouldnt have posted to comp.lang.perl.misc .
I recall that such a program was posted in comp.lang.perl.misc in 1998
sometime. I thought that I had a copy but I appear not to. I am sure
a judicious searching of Deja News will supply the answer.

This is a classic example of what Larry Wall calls "false laziness" in
his essay on the three virtues of a good programmer. Asking this question
here required getting into your newsreader, composing the subject line and
question, posting it, and (worst of all) waiting around for answers.
Conversely, doing
perldoc -q contains
on your very own system would have got you your answer immediately.
(Actually, 'contains' was the third keyword I tried, after 'exists' and
'existence' -- but three tries with perldoc -q is still vastly quicker and
easier than using the net to get answers.)

Reading the FAQ from first line to last line (or at least the questions,

I was well aware of the issue you raise, which would require a bit more
research.
Relative to PCs, the number (not the cumulative expenditure) of other
architectures is 'small'. Relative to Windows, the number of other
operating systems is 'small'. For appropriate values of 'small'.
I perceive attitudes changing around here, as people realize the
importance of PCs and other Windows-based systems to the future success
of Perl. Cheers for ActiveState!

I can't agree with you on that. Once people start using Windows-based
systems they tend to get stuck within the world of Windows, not looking
outside it for good solutions. If we hadn't had that Linux-hype more and
more "experts" would "grow up" with Windows and looking mainly at what's
available from the same source as it; and then they end up chosing
between something marketed as an web-thing and something strange and
complicated that only geeks care about.
In a short-term view it's very good for Perl to reach out to more and
more people using Windows, but there's also a long-term danger with it.
I know, I know... people will always study at universities and will that
way find their way to UN*X and so on, but more and more people work with
Internet-related things without ever going to a university, or studied
something far from related to computers... Having a single company
controlling a market is simply too dangerous to be good for anyone but
that company.

Does the Camel count? There's a nice operator precedence table
(including associativity) on page 76.

) because there is only one 'implementation'.
Actually, there are several implementations of Perl, the most
common are probably currently 5.005_03 and 5.6.0 or maybe
5.004_04. So the question is not what C<$_&--$_> means for a
particular "implementation" [a.k.a. "version"] of Perl, but
whether it will continue to mean that in the next version.
I see a strong tendancy for "if it ain't documented, it can
change". So you would be correct [IMHO] to criticize code that
used C<$_&--$_> because it might well break in a future version.
And I think that if you submitted a patch to make this more
strongly stated in the documentation, it would be accepted, and
would be a very good thing.

Well, I was thinking that, instead of overriding them, it would be more
generally interesting if you could rename them. So, if you wanted your own
function named 's', you might choose to rename the built-in 's' as, say,
'sub'. Then, when you want to add some string to the end of whatever is in
$_, you might use a line of code like this:
sub ($) { shift };
On second thought, maybe that line of code would be misunderstood.

Well, I'm glad you tried! But if anyone here has a more comprehensible
explanation than what's already in the FAQ, we'd have put it into the FAQ.
Nevertheless, I'll take a try....

Probably that's not what you want. It sounds as if you're trying to make
something that would be easier to install, configure, and get running than
perl itself. You're not likely to get that, IMHO. I say that partly
because the ActiveState port of Perl to Windows is so simple and fast to
install. (If you want something else, ask again, and we'll tell you why
compiling won't give you that either. :-)
But, if you must, have you tried perlcc yet? Be aware that the whole
compiler suite should probably not be used for anything more than
experimental purposes.
> If in LINUX, what should I need for cross compiling?
First, you write a suitable cross-compiler.... :-)

To request back copies (available for a week or so), send your request
