You do not need to do anything like that. The 'my' variables are
block-scoped, not procedure scoped in Perl (unlike AFAIK C or C#).
This means that you can do something like
while (<>) {
my %hash;
my @row = split ',', $_;
$hash{name} = $row[0];
$hash{other} = $row[3] / $row[4];
push @userData, \%hash;
}
since you get a brand new hash with a different address in every
iteration of the loop.
HTH, Jenda
P.S.: Well, you get a different address if you keep references to
those hashes. If you use the hash within the body of the loop, but no
reference to it remains after each iteration then most likely Perl
will reuse the memory. But that's irrelevant. As far as you are
concerned, you get a brand new empty unrelated hash each time.
