I am dealing with large data.
I am creating one hash table for my data.
But when I try to access the value in hash table it is giving me out
of memory.
can anyone suggest what can be problem and how can I slove it.

Problem: Your program is using more memory than ulimit allows.
Solution: either reduce the memory footprint of your program or increase
your ulimit.
There is also the off-chance that you found a bug in Perl, but you will
need very strong evidence to support that theory.

but when I am creating tht hash table there is no error.
it gives error when I try to access tht hash array.

You are correct about the '|pgnuplot.exe' statement. I decided to remove
the full physical address for that program when reporting that code and
somehow also erased the | as well.
The extent of my formal programming training involves opening and closing
files for read, write, and append, using readline and IsKeyPressed type
statements, and using the clipboard. The rest involves standard commands
for processing data, creating arrays etc.
Information regarding Filehandles, Sockets, and three argument opens etc. is
beyond my programming skill level. And the people that I am working with
know even less than I do.
What is needed here is just some simple code that can be inserted into
already running programs to improve their performance.
--- Open a pipe from program A to program B while both are running.
--- In program A, send information to program B.
--- In program B, receive information from program A and let program A know
when B is ready to receive more information.
It is my intention to improve my knowledge of programming so that the other
concepts are understandable. But the computer programming is just one part
of a larger disaster mitigation effort. And it has to wait in a priority
line. The main program involved with this effort is already fully
operational and downloadable. So these improvements are largely to get
things to work better.
As I said elsewhere, one of the high priority goals of these efforts is to
get governments and other major groups to take over the programming efforts.
But it is first necessary to provide them with demo programs that show what
the programs they will actually eventually be using are supposed to do.

What you are saying sounds reasonable. However, one of the main reasons to
have an another Perl Newsgroup would actually be to get away from the
"experts."
With many Newsgroups and in particular this one, people can be strongly
criticized for submitting "dumb" questions that waste the time of the
experts. With another Newsgroup people could post dumb questions without
having someone tell them to stop. If they were given inaccurate information
for their program questions then their programs would simply not work. The
theory that this would somehow destroy the Perl language is I believe
unfounded. It might eventually work even better because more people around
the world would be willing to use it. At the moment many people probably
choose other languages in part because they are afraid to post "dumb"
questions to this Newsgroup.
Is Perl intended only for the use of experts? I thought that one of the
original goals was to create a highly versatile and powerful language that
anyone could use.

Please only post code you have *actually* *run*.

Then you need to hire a programmer. As a general rule, people here are
interested in helping others to learn. We are not interested in
providing code snippets for free.

This is your problem, not ours. The fact you keep mentioning it is not
likely to make anyone more sympathetic.

If the charter for the Newsgroup specifically stated that it is acceptable
for people to ask any type of Perl programming related question they wished
without first reading the FAQ files etc. or using any special posting format
then I believe that the "experts" would probably leave them alone. What
could they do? They couldn't complain to the poster's Internet server.
Numerous junk advertisements etc. would probably get posted to that
Newsgroup. But I think that it would still be worth the effort.
As I asked in one of my other posts, "Is Perl intended only for Perl
programming experts? Or is it also intended for the general public, people
such as myself?"

All of this work is actually presently being done by volunteers. And that
will have to continue to be the case for at least the near future. I myself
am a volunteer who is writing code. And I created a rather extraordinary
Perl language program that contains more than 5000 lines of code. Part of
it was formally copyrighted years ago.
One of the people who is developing the code is a retired professional
computer programmer who is doing all of the work for free and who has been
extremely helpful. But he refuses to learn Perl. And so it is necessary to
develop data sharing routines so that his programs can communicate with the
ones I myself write.

Your comments are not being disputed. Regarding asking people for code, the
only way to determine if they are willing to supply it is to ask. That does
not appear to be the case. So then, that is the answer to the question to a
certain extent for this Newsgroup.
I don't object to that myself if that is what people want to do. But as I
have been proposing, it might be productive to create another Perl Newsgroup
that would allow a wider range of programming questions. Several years ago
I myself decided to go with Perl for a programming language for a variety of
reasons. One of the most important ones was that it looked like it was a
language intended for the general public. If there is some other language
that is actively supported and that contains most of the important features
of Perl then I would be happy to advise the people that I am working with to
start using that one.
That subject was recently explored in a Fortran Newsgroup. My main
programming colleague did not like any of the available freeware versions of
Fortran that he tested. And we are now evaluating freeware Basic programs.

The Posting Guidelines refer people to the FAQ and docs for very good
reasons: the "experts" would probably leave the newsgroup, leaving it to
devolve into the blind-leading-the-blind scenario another poster
described.

Perl is intended for people who are willing and able to put in the
effort to learn Perl. Part of this effort involves reading
documentation. (So I suppose I'd have to answer "no" to your last
part of your question.)

I don't have any personal objection to that. There are other languages that
are probably more for the general public. And several of us are searching
for one right now. FreeBasic is presently being evaluated. However,
several years ago it was quite important that I find a versatile and
powerful free download language for a specific application. And although
the programming effort was neither easy nor fast, Perl did get the job done.

Because no experts would be reading that newsgroup.
In fact, no one with measurable competence would be reading that newsgroup.
Are you familiar with the concept of signal vs. noise?
What you describe would have such a low S/N ratio that folks
with the ability to answer questions would not participate.
A group full of questions with no answers will not help anyone.
> As I asked in one of my other posts, "Is Perl intended only for Perl

Perl is intended only for Perl programmers.
Fortran is intended only for Fortran programmers.
Spanish is intended only for Spanish speakers.
This concept seems self-evident to most folks...
> Or is it also intended for the general public, people
> such as myself?"
If you want to write Perl programs, it is a necessary condition
that you become a Perl programmer.
If you want someone else to write your Perl programs for you,
it will be a very hard sell...
