The exit point of any PERFORM statement currently being executed is recognized
if reached; the return jump taken is the first reached. PERFORM statements
with the same exit point can be nested to a depth of two (one inner and one
outer). If they are nested deeper, they do not return correctly. The end of
a section is regarded as a separate point from the end of its last paragraph.
