Synopsis NestedCall.tst is an intermediate test (in terms of complexity) intended to be used between the SimpleFunction and FibonacciElement tests. It may be useful when SimpleFunction passes but FibonacciElement fails or crashes. NestedCall also tests several requirements of the Function Calling Protocol that are not verified by the other supplied tests. NestedCall can be used
