Re: how do I open each line of a text file into seperate arrays?

[Sherlock]

I'd try something like this:

use strict;

open (INPUT, "myFile.txt") || die "Couldn't open file: $!\n";

my @majorArray;
while (<INPUT>)
{
   my @minorArray = split('\|', $_);
   push @majorArray, \@minorArray;
}

This will store a reference to each array within one big array, called @majorArray. You can then access each array like this:

my $arrayRef = $majorArray[0];
foreach my $temp (@{$arrayRef})
{
   print $temp,"\n";
}

or you can get at all of the contents of every array like this:

foreach my $item (@majorArray)
{
   foreach my $subitem (@{$item})
   {
      print $subitem,"\n";
   }
}

If you're having trouble with references, you might want to try checking out How do I loop over a reference to an array? or simply look up references in the documentation. Or, even more simply, push the actual array into the larger array to give yourself a two-dimensional array.

Hopefully, this'll help you get going. Good luck!
