Hello!

Help greatly appreciated.

I have the following code:

sub extractData
{
    my @projects;

    push( @projects, [readOnly("$proj Data.txt"), "A"] );

    unless( $pointerProj eq "NONE" )
    {
        push( @projects, [readOnly("$pointerProj Data.txt"), "B"] );
    }

    for( @projects )
    {
        my @data = @{ $_[0] };
        my $key = $_[1];
        ...
    }
}

sub readOnly
{
    my @contents;
    my $filePath; my $file;
    my $errMsg;

    $filePath = "$path\\" . $_[0];
    $errMsg = "Unable to read $filePath: $!";

    open $file, '<', $filePath or die $errMsg;

    @contents = <$file>;

    close $file;

    return @contents;
}

My problem is that I'm not correctly passing the resultant array from readOnly() through the anon array pushed in to @projects to ultimately store and use it as @data inside the for-loop.

The error message I'm getting is "Can't use an undefined value as an ARRAY reference at (the first line inside the for-loop)".

If someone could provide me with the correct syntax and the rationale behind it I would be much obliged.

Thanks!
