+Don't try this at home! This case, the record identifier string (which is normally generated according to the rules set in I<recordId> member of the record group, or in the I<recordId> parameter) is provided directly.... Looks much better this way:
+
+ $sysno = $sess->update_record(data => $rec1,
+ databaseName => 'books',
+ recordId => '(bib1,ISBN)',
+ recordType => 'grs.perl.pod',
+ flagStoreData => 1,
+ flagStoreKeys => 1);
+
+You can notice, that it's not necessary to define a record group in zebra.cfg: you can do it "on the fly" in your code.
