You forgot the length argument to the splice function

#!/usr/bin/perl -w
use strict;

my @array = (0..4);
print "@array\n";

splice(@array, 1, 1, "value");
print "@array\n";

Use of Spllic command

2002-02-12 Thread Kevin Butters 

A real beginner here.

I have an array with 5 elements, 0-4. I want to insert
values into the array at position 2. Do I use the
splice command?

splice(@array, 1, "value");
print "@array\n";
0 1 2 3 4 5
