rflesch has asked for the wisdom of the Perl Monks concerning the following question:

Dear community,

in a Perl CGI script, how can I
(a) declare a set of 100 string variables $str0 .. $str99 in one loop in order to obtain

my $str0=''; (..) my $str99='';

(b) further down in the script, find out (in a loop) which of those are empty?
