assembly listings from yaASM and yaLEMAP. Added some debugging messages to 'make install'. Tweaked debugging messages that VirtualAGC embeds in 'simulate'. Verified buildability in Mint 21, 20, 19, 17, and verified buildability using clang in Mint 17.

## Filename: UPDATE_PROGRAM.agc
## Purpose: A log section of Zerlina 56, the final revision of
## Don Eyles's offline development program for the variable
## guidance period servicer. It also includes a new P66 with LPD
## (Landing Point Designator) capability, based on an idea of John
## Young's. Neither of these advanced features were actually flown,
## but Zerlina was also the birthplace of other big improvements to
## Luminary including the terrain model and new (Luminary 1E)
## analog display programs. Zerlina was branched off of Luminary 145,
## and revision 56 includes all changes up to and including Luminary
## 183. It is therefore quite close to the Apollo 14 program,
## Luminary 178, where not modified with new features.

# PROGRAM NAME: P27
# WRITTEN BY: KILROY/ DE WOLF
# MOD NO: 6
# MOD BY: KILROY
# DATE: 01DEC67
# LOG SECTION: UPDATE PROGRAM.
# FUNCT. DESCR: P27 (THE UPDATE PROGRAM) PROCESSES COMMANDS AND DATA
# INSERTIONS REQUESTED BY THE GROUND VIA UPLINK.
# THE P27 PROGRAM WILL ACCEPT UPDATES
# ONLY DURING P00 FOR THE LM, AND ONLY DURING P00,
# P02, AND FRESH START FOR THE CSM
# CALLING SEQ: PROGRAM IS INITIATED BY UPLINK ENTRY OF VERBS 70, 71, 72 AND 73.
# SUBROUTINES: TESTXACT, NEWMODEX, NEWMODEX +3, GOXDSPF, BANKCALL, FINDVAC, INTPRET, INTSTALL, TPAGREE,
# INTWAKEU, ENDEXT, POSTJUMP, FALTON, NEWPHASE, PHASCHNG
# NORMAL EXIT: TC ENDEXT
# ALARM/ABORT: TC FALTON FOLLOWED BY TC ENDEXT
# RESTARTS: P27 IS RESTART PROTECTED IN TWO WAYS...
# 1. PRIOR TO VERIFLAG INVERSION(WHICH IS CAUSED BY THE GROUND/ASTRONAUT'S VERIFICATION OF UPDATE
# DATA BY SENDING A V33E WHEN V21N02 IS FLASHING)---
# NO PROTECTION EXCEPT PRE-P27 MODE IS RESTORED, COAST + ALIGN DOWNLIST IS SELECTED AND UPLINK
# ACTIVITY LIGHT IS TURNED OFF.(JUST AS IF A V34E WAS SENT DURING P27 DATA LOADS).
# V70,V71,V72 OR V73 WILL HAVE TO BE COMPLETELY RESENT BY USER.
# 2. AFTER VERIFLAG INVERSION(WHEN UPDATE OF THE SPECIFIED ERASABLES IS BEING PERFORMED)---
# PROTECTED AGAINST RESTARTS.
# DEBRIS: UPBUFF (20D) TEMP STORAGE FOR ADDRESSES AND CONTENTS.
# UPVERB (1) VERB NUMBER MINUS 70D (E.G. FOR V72, UPVERB = 72D - 70D = 2)
# UPOLDMOD (1) FOR MAJOR MODE INTERRUPTED BY P27.
# COMPNUMB (1) TOTAL NUMBER OF COMPONENTS TO BE TRANSMITTED.
# UPCOUNT (1) ACTUAL NUMBER OF COMPONENTS RECEIVED.
# UPTEMP (1) SCRATCH, BUT USUALLY CONTAINS COMPONENT NUMBER TO BE CHANGED DURING VERIFY CYCLE
#
# INPUT:
# ENTRY: DESCRIPTION
# V70EXXXXXEXXXXXE (LIFTOFF TIME INCREMENT) DOUBLE PRECISION OCTAL TIME INCREMENT, XXXXX XXXXX,
# IS ADDED TO TEPHEM, SUBTRACTED FROM AGC CLOCK(TIME2,TIME1), SUBTRACTED FROM CSM STATE
# VECTOR TIME(TETCSM) AND SUBTRACTED FROM LEM STATE VECTOR TIME(TETLEM).
# THE DP OCTAL TIME INCREMENT IS SCALED AT 2(28).
## Page 1375
# V71EIIEAAAAE (CONTIGUOUS BLOCK UPDATE) II-2 OCTAL COMPONENTS,XXXXX,
# XXXXXE ARE LOADED INTO ERASABLE STARTING AT ECADR, AAAA.
# XXXXXE IT IS .GE. 3 .AND. .LE. 20D.,
# AND (AAAA + II - 3) DOES NOT PRODUCE AN ADDRESS IN THE
# 9 NEXT BANK
# . SCALING IS SAME AS INTERNAL REGISTERS.

# INCREMENT XXXXX XXXXX, IS ADDED TO THE AGC CLOCK, IN
# CENTISECONDS SCALED AT (2)28.
# THIS LOAD IS THE OCTAL EQUIVALENT OF V55.
# OUTPUT: IN ADDITION TO THE ABOVE REGISTER LOADS, ALL UPDATES
# COMPLEMENT BIT3 OF FLAGWORD7.
# ADDITIONAL NOTES: VERB 71, JUST DEFINED ABOVE WILL BE USED TO PERFORM BUT NOT LIMITED TO THE FOLLOWING UPDATES--
# 1. CSM/LM STATE VECTOR UPDATE
