However, what amount of knowledge is adequate for maintaining JES exits and simple tools from the CBT tape? More important does the person believe in testing in a safe environment and reading the appropriate manuals (and knowing whether they understand them)? When you start getting into cross memory services, I don't know that I would want to touch that code let alone things that get into locks so knowing your limitations is important.
