Yes, it's dead, the posts you see are just recycled from 1996-1997 and

I assume that each number can belong just to Table A or Table B.
If the file gets too large for the memory then use maybe a database

These are IPv4 net blocks. Storing net blocks efficiently is easy,
since they are just binary strings with a mask number between 0 and 32,
which is 5 bytes. You can then use vec() or pack()/unpack() to extract
the data or match against it. Of course, you could just use
Net::Netmask if your "condition" involves searches through net block
tables as it did the last time you asked about net blocks.

doubt not related to perl.
have large file in following format.
REGION Table_A {
17.64.0.0|17;
32.58.34.192|26;
32.58.157.0|24;
32.106.15.0|24;
52.106.32.0|21;
22.32.88.0|24;
}
I want only IP address starting with 32.
so for above list it should return 3 address:
32.58.34.192|26;
32.58.157.0|24;
32.106.15.0|24;
what expression should I use in grep

But is that really what you are looking for, or are you trying to match
two net blocks to each other? Your requirements have changed three
times now and as much as I'd like to help you, you have to actually tell
us what you're trying to do instead of asking for specific bits of
information you can easily find in the documentation.

Which is why you should declare variables in the smallest possible scope.

Or don't declare variables in a broader scope than necessary.

why is $a a global variable? if i write my $a it does not make it to a
local variable?

Because you made it so.
You declared it at file scope, so it is visible throughout the file.

Since $a was declared outside of any block, its scope is from the place
it was declared to the end of the script. That includes the foo subroutine.
There is a sense in which $a is local, but it is local to the entire
script, starting from the place where it was declared.

Your program has its own namespace. I think its brought into the Main:: namespace.
The above works because it is really this:
{
use strict;
use warnings;
my $A = 30;
print $A,"\n";
}

The above doesen't work because its really this:
{
use strict;
use warnings;
print $A,"\n";
my $A = 30;
}

Global symbol "$A" requires explicit package name at jjj.pl line 4.

Why wouldn't it be recognized? It's a normal global variable.
>They are really in the same scope.
The function definition and the variable are (not that this would matter
much), but not the _body_ of the function and the global variable. The
body may define local objects, too, which will be visible in addition to
any global objects.. This is the typical semantic for the vast majority
of programming languages, nothing special about it..
>If this is intended by the user (closures) this is
It is not a closure! Quite the opposite, actually.
>wonderful but it can cause bugs.
Yes, of course. That is why global variables are discouraged and should
be used only when there is a good reason for using them. Again, that
applies to the vast majority of programming languages.
>The only solution is to write the function at the beginning.
No!!!
First of all it doesn't work because in Perl with strictures enabled you
need to declare a variable before using it ($a is an exception, see
below).
And second it is standard best practice in any programming language to
avoid global variables unless you have a very good reason why you need
them.

It does compile and it even runs. All you get is a warning (if warnings
are enabled as they should be)
Use of uninitialized value in print at [...]
However using $a in Perl is not a good idea to begin with. $a and $b are
special in sort() and therefore excempt from several checks in
warnings/strict.
Had you used a different variable e.g. $x, then you would have gotten
the error
Global symbol "$x" requires explicit package name at [...]
Execution of [...] aborted due to compilation errors.
from strict, which is telling you that you are using a variable before
it is declared. This is much more to the point and more important the
reason why your "solution" doesn't work.
>Hope this will save from other programmers to get unexpected errors.
Hmmm, well, except your 'solution' doesn't address the underlying
problem, violates proven best practices, and doesn't work.

Aren't global variables the same thing as package variables?
And aren't those mutually exclusive with lexical variables?
The scope of the lexical variable may be broad, but that doesn't
make it global, at least not in Perl vernacular as I understand it.

Actually, I think it is a closure. It is a nasty accidental closure with
possibly undesirable consequences, for example it only closes once, at
compile time (The ability to re-close may be desirable, but by my
understanding it is not a mandatory part of the definition of a closure.
Obviously this gets into semantics, but sometimes semantics are important).
Understandably, the part of the docs that describes closures described the
*right* way to do them, not that nasty accidental way.

i have been watching this thread with bemusement and seeing the group
miscommunicate about this topic. let me try to clear up the mess. :)
if you declare a lexical (my) variable in the body of a perl source file
outside of any sub or block, it is best called a file scoped lexical. it
is visible from the point (or just after :) of the declaration to the
end of the file. you can even declare another my variable of the same
name and it will now be scoped to the end of the file (but it will
generate a warning so don't do it). these types of variable are also
called file globals as they are usually global to the entire file (even
though the declararation is lexical.
what most perl uses of global mean are what is more properly called
package globals. this means they are in the symbol table and truly
global to the entire program (as long as you know where to find it in
the symbol table, you can mung it at a distance).
so we have the lexically declared file scoped 'globals' and
program/package 'globals'. please note the difference now and when you
discuss these in the future. i won't even bring up 'our' which just adds
to the confusion by being a lexical declaration of a package global!

You are incorrect. Twice.
If it was a package variable, then it would be in the main:: package.
But it is a lexical variable, and lexical variables are not in any package.

If you don't need any special formatting,
and you output dates as "yyyy-mm-dd HH:MM:SS" strings,
then just save the resulting CSV (with proper headers) under an xls-name
like data.xls,
and most users won't even notice that the file isn't a native Excel
file.
