Well, using int(rand(10)) gives you an integer from 0 to 9. If you add 10
to it, you get an integer from 10 to 19.
To get an integer from 10 to 99, you need to come up with an expression of

In this case there are 6 elements in the array, so we want a number between
0 and 5. So try this variation on your code:
@tea = ("Meba", "Shaun", "Mark", "Jason", "Rick", "Dan");
$get = int(rand
Hrm, try this:
@tea = "Meba", "Shaun", "Mark", "Jason", "Rick", "Dan";
srand (time ^ $$ ^ unpack "%L*", `ps axww | gzip`);
print "$tea[rand(5)]\n";

I just typed the code in the e-mail. It was part of my program. Sorry.

If the code then change if( $i = $array[$j] ) to if( $i == $array[$j] )
otherwise you end assigning $i with the value of $array[$i].

Thanks for the input. The only trouble I would have with that is the file
size. My files are HUGE. I don't think the admins around here would like me
doing that. What I was thinking was to generate an array with a bunch of
random numbers in numerical order. Then run through the file and print only

Hi,
if you just want random numbers, there is a very simple function: RAND.
Works like this:
#!perl -w
use strict;
my ($varNumber);
$varNumber = rand;
print "Random number is: ", $varNumber,"\n";

I've just google'd "Random access numbers" and there is very little
there. Nothing that seems related to a
$num=(int(rand 35));
There is probably a more random way to do it, but this is what i know...

This is getting a bit of topic.
/dev/random is seeded with supposedly random events. In Linux I believe it

Hello
The easiest way to do this is using hash slices. Let me explain.
my %hash = (); # creates an empty hash
$hash{name} = 'Aziz';# set the name
$hash{id} = 512; #set the id
$hash{bdate} = '12/3/1976/'; #set the bdate
or, you can do this:
%hash = (name => 'Aziz', id => 5

Hi Sushil,

You can also look at the Math::Random and Math::TrulyRandom modules on the
