Hi all,

If I am just missing an FAQ, please forgive me, but I didn't see this in either the Q&A or via Supersearch.

I have many many subs in my program, many called sequentially, or from within other subs. Some of these down-the-line subs require inputs from the output of a sub 5 or 6 places back up the line. i.e. 

sub First {
 # do something....
 return $info_required_not_until_sub_seven;
}
sub Seventh {
 my $input_from_first = shift;
 my $input_from_fourth = shift;
 my $input_from_sixth = shift;
 #etc...
}

What I've been doing so far has been passing the variable through each and every intervening sub. I had originally made them global rather than scoped to each individual sub, but many people were suggesting that was a big drain on memory, esp since some of these are huge arrays, etc.

My question is, is there a way to hold on to a locally scoped variable, to pass it on later, or even something along the lines of :

from sub FIRST get $input_required_not_until_seventh

?

Thanks,
Matt
