I think your code is closer, but perhaps still a bit optimistic. Because the assignment of $some_play is in an until loop, it will continuously loop through and eventually get set (assuming that your randomizer has been seeded sufficiently so that it is possible for the whim to change).

However, I've found that often buy() can somehow get stuck in an infinite loop until everything crashes. Once you are stuck in the loop, control is never passed back so that $some_play can even be considered. This can crash in two ways. Either you'll get a heap overflow from the recursion, or the credit card will fail.

sub buy () { { $::not_a_good_night ||= rand; if ( $credit_card_balance > $credit_card_limit ) { die ( "Dog house tonight" ); } push @shopping_cart, shift(), shift(); buy(qw( more things )) if ( $::not_a_good_night > 0.3 ); }

    [ovedpo15]: consider the following format of strings: some_data-doesn't- matter,value. how I get the value with regex? it should be after the last comma (last string)
    [Corion]: Text::CSV_XS for all your CSV file parsing needs. Other than that, what problems do you have with perlre, and capturing everything after the comma? Also, index and substr would also work.
    [choroba]: my ($value) = $string =~ /.*,(.*)/
    [choroba]: The .* at the beginning matches the longest possible substring, so it eats any previous commas
    [choroba]: But for CSV, use appropriate modules
