And test it, too. Not sure what approach you mean. The my_words & their_words are an approach from wordlist.c but in that case we have a proper line number too (much like seq) and I hoped to avoid incrementing that. Hmm but I see this now: /* Restored session. line_number is right after a word we've actually used. */ ... /* We assume that line_number is at the beginning of other nodes' block */ Does this apply to external mode too? I mean, can I assume that I am at the start of a full "their_words" block after resuming? How/why is that? I can't see why that would be a safe assumption. A fix_state() seems to happen right before a clear_keys and if "we" are several nodes (as in -node:1-7/10) that could be in the middle of my_words. magnum
