in reply to Remove whitespace in string and maintain overall length

sprintf can append space to the end of a string: 
use warnings;
use strict;

my $len = 30;
my $address = '123   Main St    NE';
$address =~ s/  +/ /g;
$address = sprintf "%-${len}s", $address;
print ">>>$address<<<\n";

__END__

>>>123 Main St NE                <<<

    Wow. That worked the treat, thanks!

    I am no programmer, but rather pull bits and pieces from the code we have floating around. I've see sprintf, but never knew what it was. Looks like I have another Perl toy to play with.

    Thanks again.
