When you open a binary file with binmode (Filehandler),
you recive the data in $var when reading.
But to process such a data (say you want to add 1 to $var) you to convert to some other type. if you know the answer please let me know. thanks alot

perl autoconverts (or, as it says in the FAQ, 'does the right thing');

For instance:

$a = "2.00";
$b = $a + 1.0;
$c = $b -1;

if ($a == $b) {
   print "What a wonderful world";
} else {
   print "Uhoh... what happened?";
}
print "\n";

By the way, waleed, you have 3 questions locked right now, and your grading history shows a habit of letting questions auto-grade, which is oft considered impolite.  Perhaps you could acknowledge those 3 questions?

b2pi,

I am very very polite my friend. I don't mean that and I will check to see what you talinkg about. That's not my habit but sometimes they send the evaluation with wrong answer and because I am SO polite I don't reject it so fast. I let them read the comments until they might understand the question and give an appropriate answer. You see how I am not rude. Anyway I thank you for that "impolite thing".

Look at this and the answers. They send a respond something like  
Can we convert to GIF and keep z's values"
Digiwiz proposes something has no relation with what I want and he posts the evaluation!!!!!!!!!!
Jacco propses the solution and disappears since july 98 .

Are you asking about binary data as in
perldoc -f pack
If so, you'll have to know the format of the data
