hello, monks. My question is:
There is a potentially large amount of data in array @DBread and is return'd. After it is return's is the @DBread empty'd? I'm going to be forking in other parts of the program so i need as little memory used as possible. (i know i can read a file line by line but will do that later.) This is a more academic question more than a practical one

sub readDB{
    my $DBtoread = shift;
    my $FILEREAD;
    
    open($FILEREAD, "+<", "./database/$DBtoread");
    
    my @DBread = <$FILEREAD>;
    
    close($FILEREAD);
    return(@DBread);
}

thanks!
