RADAR_LEADIN_ROUTINES.agc
### FILE="Main.annotation"
## Copyright: Public domain.
## Filename: RADAR_LEADIN_ROUTINES.agc
## Purpose: The main source file for Luminary revision 069.
## It is part of the source code for the original release
## of the flight software for the Lunar Module's (LM) Apollo
## Guidance Computer (AGC) for Apollo 10. The actual flown
## version was Luminary 69 revision 2, which included a
## newer lunar gravity model and only affected module 2.
## 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. 502-503
## Assembler: yaYUL
## Contact: Ron Burkey <info@sandroid.org>.
## Website: www.ibiblio.org/apollo/index.html
## Mod history: 2016-12-13 MAS Created from Luminary 99.
## 2016-12-14 MAS Updated from comment-proofed Luminary 99 version.
## 2016-12-17 RRB Updated for Luminary 69.
