I am writing a function evaluator program to estimate a generalized McFadden
profit function with convexity imposed using nlsur. As I have been writing
this the question arose why scalars must be dereferenced like local macros.
I assume it is because of the functional evaluator program. But I can't
find any documentation of function evaluator programs. I am writing to ask
if someone can direct me to references that would improve my understanding
of this issue.
Thanks.
