Looking at good generated code from decently coded HLL programs can
give a clue.  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.
