Peng,



Could you give me an example code? I want to randomly select X numbers of
numbers from the @nums list. For instance, i want to randomly select 3
numbers from @nums i.e. 10000, 10005, 140000. How would you use srand to do
this?


Try the modified code below, it works fine.

use strict;
use warnings;
my $max=3;
my @nums = ("10000","10002","10004","10005","10006","140000","1500000");
my @randnum = map { $nums[int rand(@nums)] } 1 .. $max;
print "@randnum \n";
