Need Help with putting Hashes in a two-dimensional array

Since your data is actually started by '&BASKETZEILE1=',
'&BASKETZEILE2=', etc. I have modified the regex to include the numbers
and '='.

No need for a C-style for loop here. See below.

You will not be able to access your data in both of these ways from the
same variable. The first implies a hash reference stored in
$basket_rows[1], the second an array ref stored in $basket_rows[1]. You
can only store one reference in there. If you want to store both a
hashref and an arrayref in $basket_rows[1] then you will have to store
them in an intermediate aggregate and store a reference to that in
$basket_rows[1].
I am using an anonymous hash as the intermediate aggregate here:
$row = {
};
}

They're accessed as above, but with the extra level in between. And
there's no need to shout. A lot of courtesy copies are sent from clpm
to those with valid email addresses.
$v1 = $basket_rows[1]{Hash}{'BZ_STATUS'};
# only the value of this key
$v2 = $basket_rows[1]{Array}[2];
# the entire key=value pair
The whole thing can be printed quite easily with the right module.
use Data::Dumper;
