[J3] [EXTERNAL] [BULK] Re: Use of "base object"

[Clune, Thomas L. (GSFC-6101)]

Van,

Allowing ordinary pointer association between real and complex arrays is on the short-list for F2028 features.  So, one less reason to keep EQUIVALENCE (if successful).

I agree an interp isn’t necessary. (I also agree about deleting EQUIVALENCE😊)

There are harmless uses of EQUIVALENCE, such as two reals to a complex, or scalars to name array elements.

I wouldn't object to deleting EQUIVALENCE between incompatible types, such as integer to logical, or two reals to a double. Complex type is defined to consist of two reals, so equivalence between real and complex (with the same kind type parameter value) would be "compatible."
