But p${b}.zip is the same as p$b.zip, thus interpolating $b and eliminating the braces. If you're unsure of this, you can do the following:

my $b=7;
print ${b};
[download]

That prints 7, thus making MeowChow's solution a viable one. I know it looks odd, but it's valid Perl and it works with warnings and strict. I'm using 5.6.1. Does this fail on other versions of Perl?
