I use the scalar keyword on occasion:
#!/usr/bin/perl
my @arr = qw/adfs adsf 4fd feqw3 f432d/;
print "The size of the array is " . scalar (@arr) . "\n";

The below is speculation since these questions need to be answered. In
addition to what is @files I'd add what is $Tmp?

I had the following code:
open (FILEOUT, "> $OutDir/info") or die $!;
print FILEOUT "text = abc\n";
my $Tmp = ++$#files;
print FILEOUT "moretext = $Tmp\n";

after? Why is that
