Thanks, Peter, I understand the question better now. Based on Glenn's response and on clicking the various symbols in CNTTS (e.g., 0, 98, 99) to get explanations, I believe that the L0 listing is for MSS, such as Aleph, that contain the verse with 0 lacunae, i.e., that have the complete verse with no gaps. This is not terribly intuitive, but once you know it, it is in fact quite informative (assuming I've understood it correctly). Then, as Glenn says, the 98 listing with only A indicates that A lacks part of the verse, in this case, the first two letters; but the CNTTS explanation "Partial lacunae listed at the beginning of the verse" means, I believe, that that is where partial lacunae are listed in the apparatus, not that the lacunae are only at the beginning of the verse--cf. 1 Cor 15:45, where again A is listed under 98, and has letters missing at several places in the verse. The 99 listing, then, as Glenn stated, indicates that the specified MSS lack the entire verse.
