Any chance of an explanation of the L system. I am not as young and quick as I was. Any help would be appreciated.
The new Ks seem to be the the old ones less the level part.

Thanks.

Yes, the new K codes are only the bit values from the end of the old K codes. The new L code is not actually meant for anyone to adjust as I have processes that do that. But in any case the next Grail release has it documented as:
-- Lxxxxxxx where xxxxxxx is an integer value that represented three parts of a quest's level added together
-- The old K value * 65536
-- The old L value * 256
-- The old N value * 1

Basically what used to happen was the K, L, N and M codes were read in an an integer was made from them by parsing the strings and turning them into numbers that were part of a large integer. Instead of doing that, I am setting the integer values directly from the K, L and N codes. This makes the file smaller and speeds up processing it a bit. The M code is not included at the moment because it needs to be revisited. It may be included in the future based on findings but the few quests that have M codes are processed just as they were in the past.

Thanks, I get it now.
