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: ERASABLE_ASSIGNMENTS.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.
## Reference: pp. 91-156
## Assembler: yaYUL
## Contact: Ron Burkey <info@sandroid.org>.
## Website: www.ibiblio.org/apollo/index.html
## Mod history: 2017-07-28 MAS Created from Luminary 210.
## 2017-08-14 MAS Began updates for Zerlina 56.
## 2017-08-16 MAS Complated updating for Zerlia 56.
## 2017-08-24 MAS Fixed an incorrect offset in lunar landing erasables.

# CONVENTIONS AND NOTATIONS UTILIZED FOR ERASABLE ASSIGNMENTS.
# EQUALS IS USED IN TWO WAYS. IT IS OFTEN USED TO CHAIN A GROUP
# OF ASSIGNMENTS SO THAT THE GROUP MAY BE MOVED WITH THE
# CHANGING OF ONLY ONE CARD. EXAMPLE.
# X EQUALS START
# Y EQUALS X +SIZE.X
# Z EQUALS Y +SIZE.Y
# (X, Y, AND Z ARE CONSECUTIVE AND BEGIN AT START. )
# (SIZE.X AND SIZE.Y ARE THE RESPECTIVE SIZES OF X AND Y,
# USUALLY NUMERIC, IE. 1, 2, 6, 18D ETC. )
# EQUALS OFTEN IMPLIES THE SHARING OF REGISTERS (DIFFERENT NAMES
# AND DIFFERENT DATA). EXAMPLE.
# X EQUALS Y
# = MEANS THAT MULTIPLE NAMES HAVE BEEN GIVEN TO THE SAME DATA.
# (THIS IS LOGICAL EQUIVALENCE, NOT SHARING) EXAMPLE.
# X = Y
# THE SIZE AND UTILIZATION OF AN ERASABLE ARE OFTEN INCLUDED IN
# THE COMMENTS IN THE FOLLOWING FORM. M(SIZE)N.
# M REFERS TO THE MOBILITY OF THE ASSIGNMENT.
# B MEANS THAT THE SYMBOL IS REFERENCED BY BASIC
# INSTRUCTIONS AND THUS IS E-BANK SENSITIVE.
# I MEANS THAT THE SYMBOL IS REFERENCED ONLY BY
# INTERPRETIVE INSTRUCTIONS, AND IS THUS E-BANK
# INSENSITIVE AND MAY APPEAR IN ANY E-BANK.
# SIZE IS THE NUMBER OF REGISTERS INCLUDED BY THE SYMBOL.
# N INDICATES THE NATURE OF PERMANENCE OF THE CONTENTS.
# PL MEANS THAT THE CONTENTS ARE PAD LOADED.
# DSP MEANS THAT THE REGISTER IS USED FOR A DISPLAY.
# PRM MEANS THAT THE REGISTER IS PERMANENT, IE. IT
# IS USED DURING THE ENTIRE MISSION FOR ONE
# PURPOSE AND CANNOT BE SHARED.
# TMP MEANS THAT THE REGISTER IS USED TEMPORARILY OR
# IS A SCRATCH REGISTER FOR THE ROUTINE TO WHICH
# IT IS ASSIGNED. THAT IS, IT NEED NOT BE SET
# PRIOR TO INVOCATION OF THE ROUTINE NOR DOES IT
# CONTAIN USEFUL OUTPUT TO ANOTHER ROUTINE. THUS
## Page 92
# IT MAY BE SHARED WITH ANY OTHER ROUTINE WHICH
# IS NOT ACTIVE IN PARALLEL.
# IN MEANS INPUT TO THE ROUTINE AND IT IS PROBABLY
# TEMPORARY FOR A HIGHER-LEVEL ROUTINE/PROGRAM.
# OUT MEANS OUTPUT FROM THE ROUTINE, PROBABLY
# TEMPORARY FOR A HIGHER-LEVEL ROUTINE/PROGRAM.
