Hi there again :)
I was wondering why this doesnt work. I have an array of numbers. I use a while loop as follows to split the array. 
while(<>)
{
    @array = $_;
    @array = split;

}

This splits the array via new line. Every element of the array holds a string of numbers. The element $array[0] for example might contain the following data. 
12 44 111 445

The numbers are separated by tabs.
I now want to get at individual numbers from the element $array[0]. So, I attempted the following. 
@line1 = $array[0];
print "@line1\n"; # this works

@line1 = split(/\t/);
$var1 = $line1[0];
print "$var1\n"; # this doesnt work

[download]
$var1 doesnt print. Could anyone please tell me why and what I could try to rectify this? Thanks
