Re^4: I have a hash in a hash in a .....

Perhaps you could define "read-only", because I can certainly change $r. I can just assign it a new value. I can change the data it points to. None of those things relate to "read-only". It's the conpletely wrong way to think about it.

That $r no longer is a reference when I give it another value doesn't really matter.

I said the result was read-only. I never said `$r` was read-only. Oops, I didn't original post, but I did in my second post. Fixed. The OP wanted a means of accessing the value at "key" @k. Using the "$r" method, one cannot edit the accessed value. Using the "$p" method, one can edit the accessed value. When something cannot be edited, it is said to be read-only. So while the scalar `$r` itself is not read-only, the accessed value is read-only. Update: Added underlined text.	[reply] [d/l] [select]
