Issue 1143: Fix various symbol name and other minor typos
MAIN.agc
### FILE="Main.annotation"
# Copyright: Public domain.
# Filename: MAIN.agc
# Purpose: The main source file for Luminary 1C, revision 131.
# It is part of the source code for the Lunar Module's (LM)
# Apollo Guidance Computer (AGC) for Apollo 13.
# Assembler: yaYUL
# Contact: Ron Burkey <info@sandroid.org>.
# Website: www.ibiblio.org/apollo/index.html
# Mod history: 04/12/03 RSB. Began.
# 05/05/03 RSB. ...continued.
# 05/11/03 RSB Draft of this file completed.
# 06/08/03 RSB Drafts of all the included files completed.
# 05/14/05 RSB Corrected website reference above.
# 06/30/09 RSB Added an experimental HTML note.
# 2017-01-06 RSB Changed page-number references so that they
# refer to the markings on the physical pages
# of the printout (rather than PDF "pages" in
# the file 1729.pdf, which is no longer the
# associated reference material).
# 2017-01-20 RSB Changed GOTOP00H to GOTOPOOH in all *.agc
# files. There are probably more POO problems
# but those are the only ones I fixed.
# 2017-02-12 RSB References to the scanned assembly listing
# have been updated now that a more-legible
# scan is available than before.
#
# The contents of these "Luminary131" files were originally (2003)
# transcribed from a scanned document obtained from MIT's
# now-defunct history or recent technology website, but which can be
# consulted now at
# http://www.ibiblio.org/apollo/ScansForConversion/Luminary131
# As of 2017, however, there is a far-more legible scan, created from the same
# physical printout, which you should instead consult, at either
# http://www.ibiblio.org/apollo/ScansForConversion/Luminary131-Eyles
# or
# https://archive.org/details/luminary131agcpr00miti
# Notations within the original program listing read, in part:
#
# NASA Apollo LUMINARY 131 (1C) Program Source Code Listing.
# MIT Instrumentation/Draper Laboratory -- 19 December 1969, 1742 pages.
# This listing contains the flight program for the Lunar Module
# as created by MIT's Draper Lab for the Apollo 13/14 moon missions.
#
# This file is a little different from the other Luminary131 files I'm providing,
# in that it doesn't represent anything that appears directly in the original source.
# What I (RSB) have done for organizational purposes is to split the huge monolithic
# source code into smaller, more manageable chunks--i.e., into individual source
# files. Those files are rejoined within this file as "includes". It just makes
# it a little easier to work with. The code chunks correspond to natural divisions
# into sub-programs. In fact, these divisions are more-or-less specified by
# the source code itself. Refer to the "TABLE OF SUBROUTINE LOG SECTIONS" at the
# very beginning of the file ASSEMBLY_AND_OPERATION_INFORMATION.agc.
#
# It may be reasonably asked why tens of thousands of lines of source are joined by
# means of inclusion, rather than simply assembling the source files individually and
# then linking them to form the executable. The answer is that the original
# development team had no linker. The builds were monolithic just like this.
# There was a big emphasis on reusability of the code in the original project,
# apparently, but this reusability took the form of inserting your deck of
# punch-cards at the appropriate position in somebody else's deck of punch-cards.
# So, indeed, the method of file-inclusion is a very fair representation of the
# methods used in the original development ... with the improvement, of course,
# that you no longer have to worry about dropping the card deck. On the other hand,
# I wasn't there at the time, so I may have no idea what I'm talking about.
#
# Finally, note that the original Apollo AGC assembler (called "YUL") is no longer
# available (as far as I can tell). The replacement assembler yaYUL accepts
# a slightly different format for the source code from what YUL accepted, so the
# source code has been targeted for assembly with yaYUL.
# What follows is simply a bunch of file-includes for the individual code chunks.
# I've marked the page numbers vs. the original scanned listing (1729.pdf) to
# make proof-reading easier. Besides, the scanned listing contains a lot of
# interesting tables (cross-referenced to page numbers) created by YUL,
# but not duplicated by yaYUL, so it's still valuable even if the source-files
# listed below are in hand. Notice, though, that the page number herein are those
# the scanned (PDF) file, and not those which are marked on the scanned pages
# themselves, so there is not an exact correspondence between YUL-generated
# page numbers appearing within tables and the page numbers marked in this source
# code.
