A pair of links that is called as a dyad and that takes the pg10.txt file as its right argument and the required biblical reference as its left argument. TIO fails with the full document (presumably because the POST exceeds the maximum size), and the links to TIO on CGCC are even more limited because of length. However, it should work with the full text if run locally.

Pleasingly now code length in bytes == number of books in bible.
