in reply to How can I create an anonymous scalar?

I am confused. Do you really want an anonymous scalar?

You want to have several references to a scalar and also to be able to change the value of the scalar independently (not via the references). If so, you need to name that scalar with a scalar variable and it won't be anonymous.

Anyway, what's wrong with a straight reference to a scalar?

$v = "something"; $ref1 = \$v; $ref2 = \$v; # both $ref1 and $ref2 point to the same variable. # change the value $v = "something else"; # both $ref1 and $ref2 will point to the change +d value $v2 = "new value"; $ref1 = \v2; # $ref2 now points to a new variable # $ref2 will continue to point to $v
Have I totally misunderstood your question?

    Well, just a bit. I didn't want to change $$ref1 (and $$ref2) if I changed $v. The answer from Randal Schwartz (merlyn) is what I was looking for. Thanks anyway!
