in reply to Re: Array loops and assignments
in thread Array loops and assignments

@Preceptor: Right. I want to store each element of the array in a variable of its own. So instead of assigning it to individual variables, I was hoping to build the variable and assign it on the fly. Makes sense? Perhaps,I'm overcomplicating this... Thanks!

    Definitely overcomplicating it. Try this idiom: Think of a hash as a namespace, and its elements as variables within that namespace.

    my @array = qw( Larry Curly Moe ); my %stooges; @stooges{ @array } = ( 0 .. $#array ); print "$_ = $stooges{$_}\n" for keys %stooges;

    Or if you want numbers in the name:

    %stooges = map { 'var' . $_ , $array[$_] } 0 .. $#array;

    OK, I'll bite: Why? What are you going to be able to do with the variables that you can't already do with the array?
