The "width" of a tab character depends on your output device,
not on the programming language used to generate the tab characters.
You could however, replace the tabs with spaces yourself:
perldoc -q tab

Subject: Closing an unsaved modded Excel spreadsheet?
Message-Id: <asfgbb$pii$1@newshost.mot.com>
Guys,
I'm using Win32::OLE to load and populate an Excel spreadsheet. The tests
involved take a long time, and it's possible for the user to stop the tests
before they complete.
This leaves me with;
my template modified, which I don't want to overwrite;
a partly populated spreadsheet, which I don't want to save;
a huge spreadsheet opened, which I don't want to save and delete, as it
takes a very long time to save it.
So, I want to be able to close the spreadsheet, without saving it.
Unfortunately, I get a prompt from Excel, asying that the spreadsheet has
changed, and do I want to save it. I don't want this prompt to appear.
I have searched the web, and Google, and have found many "solutions" to this
problem. Unfortunately none of them actually work!
I have tried:
$excel -> {DisplayAlerts} = 0;
and
undef $_book;
and
$_book -> {Saved} = 1;
undef $_book;
and
$book -> Close({SaveChanges => DoNotSaveChanges});
and
$book -> Close (SaveChanges => "0");
and
$book = $excel -> Workbooks -> Close ();
undef $excel;
Does anyone know a way to do this that actually works?
Thanks.
R.

Obviously that should have been:
my $string = join ' ', @ARGV;
but maybe I meant:
use constant STRING => join ' ', @ARGV;

Subject: mask bit detection
Message-Id: <3deb60f2$1_3@news.iglou.com>
Given 0751 and the like, what is the best method in perl for determining
which "bits" are set on each byte?
I'm personally thinking subtract the highest, then the next, until lowest,
if one fails, you know it isn't set, if it succeeds, it's set. I'd figure
there's a function for this already though and didn't want to roll my own
unless I had to.
Suggetions?

Standard? What way do you mean with that?
The documentation for the DBI module comes with the modules. Part of
that installation is also a FAQ, installed as DBI::FAQ. Included in
the documentation is also a large list of web resources with more
information, the most important one probably being
http://dbi.perl.org/.
The documentation for the appropriate driver comes with the DBD::*
package that you install. If you want, you can look at the
documentation on search.cpan.org as well.

To connect to Sybase, it's exactly the same, except that you replace the
word "mysql" with "Sybase" throughout the code.
To discover things like this, use search.cpan.org, looking for a module
whose name is of the form: 'DBD::<whatever>'.
To connect to MSSQL Server, there isn't a DBD specifically for that, but
since MSSQL supports ODBC, you can use DBD::ODBC, and an appropriate
$dsn string.

From: Gadrael <news@none.com>
Subject: perl on RedHat8
Message-Id: <5qCG9.198938$NH2.13425@sccrnsc01>
Whenever I write a simple print script on my newly installed RH8 box the
text will not print to the screen unless I add in a \n character. This
never happened under older distributions of RH. Does anyone know why this
is or what has happened? It seems to be a RH8 thing since if I redirect the
output to a file and then cat the file the contents does not print but if I
use an editor I do see the output in the file. Here is an example of the
situation:
____________________________
#!/usr/bin/perl
# Hello.plx
use warnings;
use strict;
print "Hello World";
____________________________
The expected output is for the file to print but the command prompt to be at
the end of the line because the cursor is not set to a new line. This does
not happen on my new install of RH8. However if I add the \n character
(print "Hello World\n";) I get see the line. I have tried redirecting the
output of the script without the \n character and the "Hello World" out put
is there but I can only see it with an editor as the cat command gives the
same result as running the script to print to the screen.
Any ideas or knowledge of what is happening would be appreciated. I don't
want to go back to RH7.3 but this is really annoying if I am say printing
the value of a varable and the variable.
______________________________
#!/usr/bin/perl
# variabletest.plx
use warnings;
use strict;
my $test = 0xBEEF;
print $test;
_______________________________
This will only print the number 48879 if I change the last line to "print
$test, "\n";
Thanks in advance for any help with this annoyance.

Doing
export PS1="$ "
should give you a clue as to what is going on.

Could one of you point me in the right direction for learning more about

i have a book which involves the m// & s// and i don't understand the use of

You might start with the documentation that ships with Perl. Try
perldoc perlretut (a tutorial)
perldoc perlre (the reference)
Regular expressions are quite well covered since they have been, after
all, a rather integral part of Perl for a long time.

Get rid of the book, then, and check out the documentation you get with
Perl:
perldoc perlretut
perldoc perlre
