Joe, Maybe your iPhone scrambled some of your message as I am not 100% sure I understand what you typed - however :
"User Key" when used as a "no-no" in CSA terms is a storage key that allows a problem state program in Key8/9 to alter the storage contents. This is not to be confused with a non-zero key (1-7) that is available for use by non-problem state callers. If you have to front-end ATTACH, then there are much better ways to achieve what you want rather than obtaining Key8 CSA.
