Thanks for all the wise monks help on my earlier dereferencing question. As I said I have inherited the code I am working on which is the root of my problems. I've knocked up some code which demonstartes the way this code works and would really welcome comments on its style. 

my $response = 1;
doSomething(\$response);
#check the reponse and do something else

sub doSomething{
    my $lResponce = shift;
    #..do something which fails
    $$lResponce = 0
}

Coming from a more formal (ADA, Java) background I would favour a return from sub doSomething, but are there advantages in this way of doing things, that I am not aware of.
Thanks for your wise words.

Update
The real subs are passed many referances some of which are changed some not, does this change anything significantly, Or would an array of return values work as well.
Thanks for the advice so far.
