Hi Lance,
You might want to re-examine this view. The process of passing by reference is not
something to just resign yourself to. It i
you're probably right. Danger, Will Robinson! ;-)

Very few things are impossible in Perl. I remember to have seen some
way to access the lexical variables of the calling subroutine. If I

Thanks guys! I did not think that it was possible, but some Perl guru
might be able to prove me wrong. I just did not want to pass references
into the subs, as a) I have nested loops, with nested subs b) Looking for
an easy way to do it. c) growing my meager Perl skillz.

Is there a way to access the 'foreach' variable from a subprocedure called
from inside the loop whose variable you want to access? Hooboy, even I
don't understand that question! ;-) An example is neccessary, I believe:
foreach my $store( values %$server ){
