There isn't such a thing as a packed date field.

The other day I was discussing the differences/advantages of packed
numerics vs. zoned numerics in physical files.
This was brought up by the fact that zoned becomes packed during the
compile unless explicitly defined.
One of the benefits of packed is that it is supposed to perform better.
What other reasons are there for this?
Also, consider packed vs. binary.
I understand that if I define a binary field in a physical file the
compiler will convert it to packed. Is it true that the packed field is
then converted to binary to be processed at the MI level (or somewhere
down
there) to be reconverted back to packed on the way back up?
