Retrieiving DB with a list file

[Hironori Kawai]

Hello

When I retrieve some entries from databases using a list file
(e.g. seqret @listfile) which consists of both retrievable USAs and 
irretrievable ones, I meet a kind of problem.

If the top-line is a retrievable USA,
I can get all retrievable entries, skipping non-retrievable ones.

In contrast, if the top-line is irretrievable, programs
stop immediately without retrieving any entries inspite of the
existence of retrievable USAs on the following lines.

I want to make the programs not to terminate even if 
the top-line is irretrievable.

Thanks
