## Purpose: A section of Artemis revision 071.
## It is part of the reconstructed source code for the first
## release of the flight software for the Command Module's
## (CM) Apollo Guidance Computer (AGC) for Apollo 15 through
## 17. The code has been recreated from a copy of Artemis 072.
## It has been adapted such that the resulting bugger words
## exactly match those specified for Artemis 071 in NASA
## drawing 2021154-, which gives relatively high confidence
## that the reconstruction is correct.
## Reference: 424
