Q,R-AXES_RCS_AUTOPILOT.agc
### FILE="Main.annotation"
## Copyright: Public domain.
## Filename: Q,R-AXES_RCS_AUTOPILOT.agc
## Purpose: A section of Luminary revision 116.
## It is part of the source code for the Lunar Module's (LM)
## Apollo Guidance Computer (AGC) for Apollo 12.
## This file is intended to be a faithful transcription, except
## that the code format has been changed to conform to the
## requirements of the yaYUL assembler rather than the
## original YUL assembler.
## Reference: pp. 1432-1449
## Assembler: yaYUL
## Contact: Ron Burkey <info@sandroid.org>.
## Website: www.ibiblio.org/apollo/index.html
## Mod history: 2017-01-22 MAS Created from Luminary 99.
## 2017-01-31 RRB Updated for Luminary 116.
## 2017-03-14 RSB Proofed comment text via 3-way diff vs
## Luminary 99 and 131 ... no problems found.
## 2017-03-16 RSB Comment-text fixes identified in 5-way
## side-by-side diff of Luminary 69/99/116/131/210.
## 2017-08-29 MAS Fixed a label (X0RULGE instead of XORULGE) and a
## comment text error found while transcribing Zerlina 56.
