Re^3: Referencing/returning array of hashes from sub

Dereference your references as you need to work with them. There's no syntactic need to expand them into non-references. Instead of:

my @expanded = @$reference;

for my $element (@expanded)
{
   ...
}
[download]

... you can just as well write:

for my $element (@$reference)
{
   ...
}
[download]

Thanks, I've managed to fix my problem now (at last!). Thanks for the help. Scrapping the big `my (@date, ...) = (@$date_ref)` [download] and replacing with `my @date = @$date_ref; my @F_SCORE = @$F_SCORE_ref; my @F_SCORE_BOX = @$F_SCORE_BOX_ref; my @F_ROA = @$F_ROA_ref; my @F_CFO= @$F_CFO_ref; my @F_dROA = @$F_dROA; my @F_ACCRUAL = @$F_ACCRUAL_ref; my @F_dLEVER = @$F_dLEVER_ref; my @F_dLIQUID = @$F_dLIQUID_ref; my @F_EQOFFER = @$F_EQOFFER_ref; my @F_dTURN = @$F_dTURN_ref; my @F_dMARGIN = @$F_dMARGIN_ref;` [download] did the trick (although I'm not sure why).

although I'm not sure why Array assignments are greedy, just as other people have said. How is Perl to know that in: `my (@date, @F_SCORE, ...) = (@$date_ref, @$F_SCORE_ref, ...);` ... `@date` should only slurp up the elements from the flattening of `@$date_ref` into a list? By the time the assignment occurs, Perl has forgotten how many elements `$date_ref` contained. By the way, as I wrote before, there's no obvious and particular need to perform this copying operation. It's probably just busy work. If you're having trouble figuring out how to work with references in place, ask away and we'll help you figure out how to avoid it.	[reply] [d/l] [select]
