Hi Sabastian,
OK, I've gotten it to work now simply by fixing my for()
loop as you
explain. This is what John was saying as well -- the loop
calling
yaz_record() shouldn't start at the first item in the subset
I
mistakenly thought yaz_range() defined, it should start at
the desired
offset in the entire result set.
Thanks very much,
Mark
