Hello Arbiters of Good Hope,

I am a relative newbie to any kind of coding and just took up using perl after learning the basics in python.

I've not quite got the hang of the 'for' loop syntax; say for example this chunk of code:

use Text::CSV_XS qw(csv);
my @sig;

print "Enter file name: \n";
my $file = <STDIN>;
chomp $file;

my $csv = Text::CSV_XS->new({binary => 1});
open (INPUT, $file) || die("Could not find $file"); 
while (my $line = <INPUT>)
## Pushing values from csv into the array
{
    push @sig, <INPUT>, $_;

for (my $i; ($i<=scalar @sig); $i++){
    for (my $j=($i+1); ($j<=scalar@sig); $j++){
        print "@sig[$j]\n";

    
    }
}

close;

}

Brings me back a compilation error referring to the for loops, as far as I can see they look correct but what the hell do I know. Can anyone help a poor man out of his blind state?
