Yes Sven, but this is the way in which all type of functions work, for
example,
<hansl>
function scalar a()
scalar b=2
return b
end function
nulldata 6
a()
</hansl>
the a() invocation does not save the result,
You almost had me there Ignacio, but not quite, because after your
function definition this line:
series look = log(a())
of course will work and use the call a() fruitfully. In fact, this
anonymous retrieval of the return value was exactly how this whole
discussion started, because *only* list-returning functions have been
the exception (since Feb 2015).
I will get back to the rest of your message later, right now I don't
have the time.
cheers,
