Did you try it? I just did and the following code seems OK:
----------8<----------CODE---------->8----------
use strict;
use warnings;
# Some test data
my $var = 'abcdefghijklmnopqrstuvwxyz1234567890';
# The the command from the question
$var = substr $var, 10, 20; # Assign variable to it's own string
# Print the results
print "$var\n";
# Below is a silly regex to do the same thing.
# It was my backup plan if the above didn't work.
# I do NOT recommend this approach. I was just
# curious if it would work. -Gerb
#
$var = 'abcdefghijklmnopqrstuvwxyz1234567890';
$var =~ s/.{10}(.{20}).*/$1/;
print "$var\n";
__END__
----------8<----------CODE---------->8----------
