Issue 1143: Fix various symbol name and other minor typos
CONTROLLED_CONSTANTS.agc
### FILE="Main.annotation"
## Copyright: Public domain.
## Filename: CONTROLLED_CONSTANTS.agc
## Purpose: A section of LUM69 revision 2.
## It is part of the reconstructed source code for the flown
## version of the flight software for the Lunar Module's (LM)
## Apollo Guidance Computer (AGC) for Apollo 10. The code has
## been recreated from a copy of Luminary revsion 069, using
## changes present in Luminary 099 which were described in
## Luminary memos 75 and 78. The code has been adapted such
## that the resulting bugger words exactly match those specified
## for LUM69 revision 2 in NASA drawing 2021152B, which gives
## relatively high confidence that the reconstruction is correct.
## Reference: pp. 53-69
## Assembler: yaYUL
## Contact: Ron Burkey <info@sandroid.org>.
## Website: www.ibiblio.org/apollo/index.html
## Mod history: 2019-07-27 MAS Created from Luminary 69.
## 2019-07-27 MAS Updated J4REQ/J3 to match LUM69 rev 2.
## 2020-12-14 RSB Tweaked the annotation relevant to the
## change mentioned above to conform to the
## style and extent of similar justifying
## annotations previously added to
## Comanche 44 and 51.

## <b>Reconstruction:</b> In Luminary 69, the following line reads "2DEC 0".
## It has been changed in Luminary 69/2 due to incorporation of the R-2
## Lunar Potential Model — see
## <a href="http://www.ibiblio.org/apollo/Documents/LUM75_text.pdf">LUMINARY Memo #75</a>.
## The Luminary 69/2 version of the line has been taken from Luminary 99/1, which
## also incorporates the R-2 model. As for the question of how it was <i>known</i>
## during the reconstruction process to target this specific value, the bulk of R-2
## model code changes are confined to the <a href="ORBITAL_INTEGRATION.agc.html">ORBITAL
## INTEGRATION log section</a>, and indeed J4REQ/J3 is used <i>only</i> there. Thus,
## after ORBITAL INTEGRATION modifications were made, it would only be natural to check
## that the constants which the ORBITAL INTEGRATION code referenced had the expected
## values relative to Luminary 99/1.
