Hmm. But if you start your scan from the just "a" that will yield the
same start-point. Remember that the term in a scan "query" is not
searched for, just used as a start-point within the list of all
terms. If you want to start from the very beginning, you should
probably use the empty search-term "", which sorts to the start.

And is it working?
empty search term is not working.
What works best is "0".

For some reason, you can't set multiple options in a single call like
this: the second and subsequent are ignored. Use:
$conn->option(preferredRecordSyntax => "usmarc");
$conn->option(number=>100);
Thanks for this very valuable information.
It works now.

Not that I know of. If there is a way, it's Zebra-specific, and Adam
will be the one who knows about it.
Let us wait his advice on that then.
