Maybe I should say why I am asking this. It just seems like STRANGE to
me that the person who programmed stata to work the way it does
INTENTIONALLY allows us to do :-

egen x=max(y)

but does not allow us to do

local x=max(y).

It just seems counterintuitive and a waste of memory. Seems unlikely
that the guy who programmed this did not think of this. That is why I
think that I am missing something.

Thank you,
Ashim.
