There are 2 minor details to be addressed. The rand(1000) function will return float values from 0 and never reaching 1000. So we need to chop off the fractional part - that will yield ints from 0..999. To get the desired range, adding a constant offset of 1 will do the job.

#!/usr/bin/perl
use strict;
use warnings;

print "",int(rand(1000))+1,"\n" for (1..100);

I'm tempted to argue that the OP didn't mention wanting integer numbers between 1 and 1000 :P, but technically I did understand the same as you until I started thinking about an answer to your post :D. I didn't mention int on purpose for two reasons, I knew it was mentioned in the rand page, and I expected GHMON to come back here for corrections if the first attempt didn't work as expected.

I think the OP wanted integers (1..1000).
I also expected a reply with some Perl code and an explanation of why it didn't "work".
I think we are on the same page...

If I get a response like "this worked", but it doesn't create an array and I haven't tried to do that...this will fall upon some very deaf ears.

Update: I am probably not the only Monk who wonders what the OP is going to do with this array of numbers? Geez.. this function is not exactly a masterpiece of Computer Science. I have no idea of how this data will be used.
