## Purpose: A section of Comanche revision 044.
## It is part of the reconstructed source code for the
## original release of the flight software for the Command
## Module's (CM) Apollo Guidance Computer (AGC) for Apollo 10.
## The code has been recreated from a copy of Comanche 055. It
## has been adapted such that the resulting bugger words
## exactly match those specified for Comanche 44 in NASA drawing
## 2021153D, which gives relatively high confidence that the
## reconstruction is correct.
## Assembler: yaYUL
