Dear Perl experts,
The following subroutine contains a while loop that continues to
multiply $p by 2, until some condition is met.
(It's for computing a Collatz tree)
$p turns 0 in this loop, however, and it remains zero for ever, of course.
My question is, what is exactly its maximum value? As

Thank you, John!
I see the limit is 32 bits now.
I just added 'use bigint', how easy!
Further, I was wondering about why you said I wasn't just multiplying by
2 using $p=1. Isn't it exactly equal to $p*=2 ???
This has anything to do with overflow or the representation of a number?
I though

Hi,
I would like to create a matrix 9x9 where the elements are list (array).
(like a cube)
These lists will decrease during processing and will normally contain one
element, so to know if a list is definitely treated I need a flag.
So 2 solutions seems to be good, but which one do you think

Why? You can find the size of an array like so:
$size = @array;
In the case of an array reference, it's merely
$size = @{
Hi,
I just got another idea witch consist to use a continuous array for lines
and columns (that is the first element of the second line is at index 9).
This array contains always 2 possibilities: array with special value for
flag or hash with 2 keys
Another idea ?
Thanks

I'm using XML::Simple to parse a very simple XML file and dump the data

You are correct. The two forms are exactly equivalent. see:

First off, realise that a pdf isn't just a marked up text document.
It's a wrapper for images and text, movies and many other formats.
If you have a text pdf, then the text is a postscript object catalogued
somewhere within the pdf.

I have seen a program named pdftotex that can extract the text from .pdf
files, and that program can be used in a perl program for extracting the
text from more .pdf files.
Search with Google for it.
I have seen that it can extract the text even from some pdf files that have
