Does (code => 'u', pos => 0) mean "the first subfield u" (which is what I take it to mean) or "subfield u if it's the first subfield" (which it might sound like outside the context of this discussion)?I had the same thought. To me, 'occur' has a clearer meaning in that context, "the zeroth occurrence of subfield 'u'", while 'pos' has more of the ambiguity described above. So of the two, I'd prefer 'occur', but I can live with 'pos'. Synonyms perhaps? (Unless someone has a need to delete the third subfield regardless of code? I never have, so perhaps not.) -- Brad
I think it should mean "the zeroth occurrence of subfield 'u'", since specifying which of a repeated group of subfields is a realistic task, as you say. For example, each record has two 'u's but all of the first ones are garbage.
