Without insulting, this proves you don't understand usenet. And I
really get "annoyed" when people "quote" words "unnecessarily." Is
"responsibility" is so "foreign" a word that you feel it necessary to
"quote" it? See the signature below.

I missed the beginning of the thread, but was there an actual Perl
question? Someone appears to have asked how to get the length of a
scalar, and I assume he was given the standard 'perldoc -f length'
response. Here we have HTML and PHP. I do hope you intend to change
writing your dynamic web documents from PHP to Perl.

I just wanna add that I think you may have interpreted that 1st quote
wrongly.
I wasn't saying that because I am 13 I cannot be called an idiot, I was just
pointing out that my wife could not call me an idiot as I am 13 and have no

I know I am getting boring now, but I really don't see why the huge group of
programmers are literally taking the piss out of me. I am new to newsgroups
so instead of slagging me off because I post HTML, someone could just tell
me not to, and then I would willingly turn off HTML posting which I have now
done.
And as for the quoting, I will quote whatever I like. There is no English
rule against it.

Are you sure you don't mean Perl vs ELISP? Emacs is an editor that I
use to abuse Perl. Actually, I use XEmacs, but nobody cares what I
do.
You might want to look at Tcl:

If they get there server back up ;-). They make some grandiose claims
wrt to Tcl vs Perl. There is also comp.lang.tcl. Have fun.

Subject: can't sort hash value
Message-Id: <39D5F435.2A13E59@corp.sunday.com>
Hi,
I need some help with the sort hash by values, following the perldoc
example
Here is my program and error message:
60 my $key;
61 foreach $key (sort { $diskio{$a} <=> $diskio{$b} } keys %diskio)
{
62 printf "%4d %s\n", $diskio{$key}, $key;
63 }
64
Can't use "my $b" in sort comparison at ./foobar.pl line 61.
Any idea? I've tried different version of perl and have the similar
error message. I'm using
perl 5.005_3 on Linux Mandrake.
Thanks & Regards,
Chris

You have declared $b as a lexical variable using 'my' somewhere in your
program. The $a and $b used by sort are global package variables
reserved for sort comparisons, and your my $b declaration masks
$main::b. The best thing to do is to remove the 'my $b' declaration or
change your lexical $b to some other name if you need that variable for
something else (preferable). Otherwise, in sort, specify $main::a and
$main::b.

Someone else has already given you an explanation but I thought I would
give you a hint as to how you can figure out these things for yourself.
Call it a fishing lesson. If you "use diagnostics" then it will give you
an explanation of what you did wrong, or if you prefer you can run them
through the "splain" program which will do the same thing:
[gwyn@thislove:~]$ splain
/usr/local/bin/splain: Reading from STDIN
Can't use "my $b" in sort comparison at - line 4 (#1)
Can't use "my $b" in sort comparison at - line 4 (#1) (#1)
(F) The global variables $a and $b are reserved for sort
comparisons.
You mentioned $a or $b in the same line as the <=> or cmp operator,
and the variable had earlier been declared as a lexical variable.
Either qualify the sort variable with the package name, or rename
the
lexical variable.
[gwyn@thislove:~]$
Hope that helps.

Depends on your ActiveState Perl version:
Build 5xx on source 5.005: http://www.activestate.com/PPMPackages/5.005/
Build 6xx on source 5.6:
http://www.activestate.com/PPMPackages/5.6/
The bad news is that it's not yet compiled there under 5.6 :-(
I'm also waiting.
You migth look at CPAN (or mirrorsites) and find it there. But I'm not
sure if it's
updated to Perl-version 5.6.

Maybe best to ask Mr. BBIRTH directly (Bill Birthisel)

It's a set of keys, each of which has a value associated with it.

Well then, that's what's stored there -- a reference to an array or a
hash.
If you'd like to see the whole data structure, there are two easy ways
to do it. Either go into the debugger ("perldoc perldebug") and type
something like "x \%grp_data" at the appropriate point, or use
Data::Dumper ("perldoc Data::Dumper").
Or, if you want, recursively search the space yourself and use ref() to
figure out how to deal with each scalar.
Hope that helps.

You have an Associative Array.

You created this Associative Array or programmed your

you not know what it contains?

Programming your script to display the
contents of this Associative Array would
be quite logical.
> Is there a way to find out the exact structure of the hash as well?
No, not really. Perl core creates arrays per a set of
rules which are quite flexible. These rules establish
an array structure based on efficiency and speed of
access for perl core. An array structure within perl
core looks nothing like what you might assume. If
you could see this structure, in what way would
this benefit you? You cannot change this structure
and regardless of how an array is structured, your
program will still display the same behavior.

Oh.

You are clearly not correctly referencing your array.
I've never had this word "HASH" returned under a bad
array reference. Interesting.
> any help please
Best help is to help yourself. You have provided no
parameters with which to work. You have not stated
what type of Associative Array with which you are
working nor how each element of your Associative
Array is delimited. Assuming your array name is
@grp_data, assuming you are using a colon as an
element delimiter, assuming only two variables
per element and assuming your Associative Array
is standard issue one dimensional,
foreach $element (@grp_data)
{
($key, $value) = split (/:/, $element);
print "$key = $value\n";
}

Upon reading, I seem to remember that even using Redmondware's Outlook
Express, email defaulted to HTML, but news defaulted to text. If Mark's
puta came this way, that would require someone, I'm not saying who,
going into Tools->Options->Send and changing the News setting _to_ HTML.
I understand the concept of "Ooh! Neat! I can post in color on Usenet!"
But I also understand that within 3 seconds of my first HTML news post
to clpm, I got a form letter from Tom Christiansen himself (or his computer
anyway) stating that I should not post in HTML, and cited several
sources backing up his claim. If you haven't already received this
letter, you might try forwarding a few of your comments to him; it would
be most enlightening.
Since then, both email and news posts are both in plain text. I use no
formatting which can't be reasonably duplicated with a few spaces in
plain text.
Not to mention, you get the added benefit and luxury of _not_ having an
entire community flaming you.
OTOH, if you want to be right _that_ much, by all means continue the
thread and face consequences.

Hello,
I am running gcc version 2.95.2 on a Solaris 8 box and cannot get
several Perl modules to compile.
HTML-Parser-3.13, for example returns:
cc -c -xO3 -xdepend -DVERSION=\"3.13\" -DXS_VERSION=\"3.13\"
-KPIC -I/usr
/perl5/5.00503/sun4-solaris/CORE -DMARKED_SECTION Parser.c
cc: unrecognized option `-KPIC'
cc: language depend not recognized
Similar errors from other modules. I have a symbolic link from gcc to
cc.
I have compiled apache and qmail today so I don't think it is a problem
with the compiler.
Suggstions, comments?
Many thanks!

Anything whatsoever assigned to a scaler is true except "0", "", and

Without insulting, this proves you don't understand usenet. And I
really get "annoyed" when people "quote" words "unnecessarily." Is
"responsibility" is so "foreign" a word that you feel it necessary to
"quote" it? See the signature below.

I missed the beginning of the thread, but was there an actual Perl
question? Someone appears to have asked how to get the length of a
scalar, and I assume he was given the standard 'perldoc -f length'
response. Here we have HTML and PHP. I do hope you intend to change
writing your dynamic web documents from PHP to Perl.
