I haven't really checked, to be honest, but I would guess that in a
large program it would be quicker because there are fewer variable
declarations, so the compiler doesn't have to allocate space for variables
that will be destroyed right away anyway (if they are lexically scoped, as
they sh

I hate to say it since you just bought a book, but you might find that
you'll have more luck with a book that is more focused on Perl in general.
If that is the book that I am thinking of, it has more to do with how to
apply knowledge of Perl to a Win32 environment. Everyone has their
favorite,
That's a very cool way of using that while loop and array. I got to see about
using that. Is it considered any quicker or less memory intensive?
If you wanted to use shift to make an equivalent routine to Ex #1, you could
do it like this:
sub makeArray{
while(shift @_){
print $_."\n";
}
}
That way if you called the sub like this...
&makeArray('hello','world','!');
You should get this...
hello
world

You know... all of those FAQs are also distributed with

chmod 755 * <- for all files
chmod 755 *pl <- for all files with a .pl extension
chmod -R 755 * <- all files and recursively through all sub-directories

Thanks

I would be in much apreciation to whomever could point me to a good learning on
formating output, but using standard fonts.
even PCL would be ok. My ultimate goal is a word doc converter if some one knows of a
good pm. Please let me know thanks.

Thomas,
Any editor (I use notepad, WinVim, and anything else available - later
you may find reason to look for a 'better' editor and there is always plenty
of opinion available about editors).
With windows, you can set a file extension association by clicking in My
Computer, View, Options.
I have seen Ex #1 "corrected" (as being more well written) to Ex #2. In
this case it is just being passed a $ but the data being passed was
irrelevant. (though not a ref) I still don't see why, i guess i don't

You need to install Perl (if you haven't). If you're on Windows, and have
never programmed before, hopefully, you have downloaded Activestate's
binaries, - they have an MSI to install everything.
If you install using Activestate's MSI file, .pl will already be associated
with the perl.exe program
Hallo, first: I´ve never programmed, bevore.
Now i want to start programming with perl. I´ve made the download of a standard perl

In the above example i had to escape the quotes to use them.
There's nothing wrong with escaping quotes, but Perl has enough quote
notations that it is almost never a "have to" to escape them. You could
define your variables like this:
