This is literally the entire code. Not sure what more you were expecting. I have left in accessing inside and outside the sub to demonstrate the inconsistent syntax. Particularly inside the function, the new syntax is not helpful, and is more than confusing because I have to pay attention to the front and back of hashes.

Additionally, in upper function, I must use \%{} if I want to pass the hash reference - and it must be bracketed because of precedence compared to the first $.

    You have repeatedly failed to answer my questions, or to provide a short, complete, self-contained example, or to explain exactly what your issue is.

    I'm out.

    Dave.
