I'm I correct assuming only the first 80 byte segment from say
"COMMENT" BLOB SUB_TYPE TEXT SEGMENT SIZE 80
since it can be read in one transfer along with the rest
of the row ?

The remaining segments require a looped transfer mechanism ?

I did some tests. Showing a grid with editable fields and a
blob present. It populates and manupulates a lot faster if you
bring up the blob for editing with a generated select into
a TRichEdit at moment of selection than relying on an automatic
process with TRichEdit being one of the displayed grid objects.
