Re^2: accessing array items

in reply to Re: accessing array items
in thread accessing array items

Yes, I guess this is a question on how to manipulate arrays in Perl. The data is in a text file. The code looks like this:

foreach (<>)    
{
    $line=$_;

    if ($line =~ m(^\s{2}[-0]))  #gets us to required lines in dataset
                                
    {
            
        chomp $line;
        @items_in_line = split ' ', $line;
            
    }

print $items_in_line[o];
}

Prob is, I cant seem to get at the individual numbers on each line.
thanks again!

`$items_in_line[3]` would give you the fourth value on the line. (Indices start at 0, though you can change that if you need to.) Be careful to make certain there really is a fourth value before you try to manipulate it. ($#items_in_line is the number of elements in the array.)	[reply] [d/l]
