I don't see this as misleading if anything it makes a simple list of a
dictionary much more obvious as all D types for the same location are
listed together as opposed to having to SEARCH the DICT for references
hidden in I types. I can't speak to A or S types as I've never used
them.
But to the point, the preference for D over I was performance, I-types
take roughly 3.5x longer to execute that the corresponding D-type.
On an older/slower box churning through very large amounts of data this
can have an impact.
I reran the timings since the original post on our current machines (
this process has been around for a few hardware/software generations )
and the 3.5x still holds but the overall impact has decreased to the
point where this issue is pretty much moot.

I wonder the same thing. All he's doing is converting a D type to a
correlative and in that case I would much rather have it an A or S type
so
you don't have to be misled by the type and not looking for the special
coding in field 3.

Hi Gerry,
Out of curiosity, why are you against I-types?
