Hi,
I sure hope this isnt in the FAQ because I could not find it. I am in need of
something to help me sort Kanji. I can think of a couple of ways to do it,
however if it is already out there why reinvent it.
Thanks in advance,
Bill Robinson

Subject: MLDBM tie failed
Message-Id: <6qcgb1$kji$1@nnrp1.dejanews.com>
I am using MLDBM (with GDBM underneath) to provide me with a cheap
and "simple" database for my AIX based web application. I am
not too familiar with MLDBM as I have only been using it for a
few weeks but I am stuck with this problem:
MLDBM error: Second Level tie failed, "The file access permissions do not
allow the specified action." at <scriptname> line 40
Now my line 40 is a tie command
tie (%THESETDATA, MLDBM, $filename, &GDBM_WRCREAT,0640);
My problem is that I don't fully understand permissions. I need some pointers
to what I should be reading. The file permissions on the mldbm file (and
directory) are "a+rwx". I don't understand when I should be using
GDBM_whatever and when I should be using O_whatever (O_RD for example). Does
0640 play any part in this if the dbm file already exists and I am not
creating it?
Much appreciation in anticipation

Subject: Newbie: changing system shell on NT
Message-Id: <ApmQwRmSMV9F0=mkU0@transarc.com>
Using any version of Perl on Windows NT, I need to be able to have
system execute its commands in an sh shell. The version of perl also
needs to support the Process module for win32 as well (if not for this
constraint, I would be very happy to use mks perl).
In the Activeware port of perl, one can set the shell that system
executes its commands in by setting the ComSpec environment variable
to the desired shell. However, this mechanism automatically passes a
/c switch to the shell command, which sh.exe is incapable of dealing
with.
Is there an environment/registry variable in the Guru port of perl for win32
that I can set to control the shell that system and backticks operate
in (the default seems to be cmd.exe)?
I've looked through all of the documentation and FAQ's, but I can't
seem to locate any information on how to change the Guru port's
default shell.
Thanks in advance.

The perlre document implies that the entire pattern is affected by the
embedded match ops. Here's the section in question:
(?imsx) One or more embedded pattern-match modifiers. This is
particularly useful for patterns that are specified in
a table somewhere, some of which want to be case
sensitive, and some of which don't. The case
insensitive ones need to include merely `(?i)' at the
front of the pattern. For example:
$pattern = "foobar";
if ( /$pattern/i )
# more flexible:
$pattern = "(?i)foobar";
if ( /$pattern/ )
Here, the use of (?i) is given as semantically equivalent to /i.

I have reviewed this newsgroup for years.... and never posted a question.
Why? Because they are really not very helpful. It is nice... an unhelpful
news group. Read the FAQ... they expect for people who are not specialists
in the
language to become one. It is funny listening to them speak among
themselves...
I wonder why Larry does not frequent... etc...etc. Why? because he taught
a group

now we have a group of Monsters monitoring a news group. Do you want some

GSAR's binary distribution of 5.004_02 does indeed come with a working
perldoc. 5.005 builds on Win32 boxen, and also includes a working
perldoc.

if that's really the first line of your program, it's a poor choice.
Try something like this:
#!/usr/bin/perl
IOW, the webserver has no way of knowing it's a perl program unless you
tell it so.

Then I would spend as much time as necessary in the course teaching
them *how to learn* Perl, since IMHO no-one who "[has] no knowledge of Perl
at all" is going to learn enough in one day to decipher someone else's
code if that code uses references. They may be able to muddle through,
but more important is that they have the tools to get up to speed, so
get them each the Camel and Llama, go over perldoc and web interfaces
(preferably hands-on) to same in detail so they can find the answers to
their questions after the course as rapidly as possible.

Even though the C output of the perl compiler does put its
pre-computed data in the initialized data area, (as opposed to a
constant initialized data area) and it does modify that data, that
doesn't mean that it can't be shared between processes. If an OS
combines demand paging with copy on write, it could make the
initialized data area shared until written to. (In which it would then
copy the page and then write to its private un-shared copy) And the
perl_init function created by the compiler doesn't seem to touch _all_
of the initialized data that the compiler creates.

Here I was talking about a shared perl library for compiled
scripts. If you have different scripts compiled into an executable
sharing the same perl library and run one invokation of the each
executable, you have one copy of the shared library. If you have
different scripts compiled into executables each linked to a static
perl library, then you have one copy of the library in each
executable. (And if you have N different scripts running
simultaneously, you have N copies of the code in memory)

It's also available to order from O'Reilly <http://www.ora.com> but when I

.* matches 0 or more characters, (?=(.*)) doesn't. Think of the (?=)
construct as saying "I'm not really matching anything, I'm just taking
a peek to see what's next". So the actual matching part is everything
between the // except for the (?=(.*)) construct ;).
And once you've got that, it should be relatively easy to find the
corresponding case in the split docs.

me with two options: 1) keep on with this group 2) change to the
moderated one.
If you have opinions on this, send them to
perl-users-request@ruby.oce.orst.edu.
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send

The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to

sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
