## 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.

# THIS LIST IS MAINTAINED TO ENSURE THAT CERTAIN ERASABLE LOCATIONS
# ARE LOCATED AT A SPECIFIED DISTANCE FROM ANOTHER ERASABLE LOCATION
# AS REQUIRED BY THE STRUCTURE OF THE DOWNLINK LISTS:
#       1. IF A LOCATION IS THE SECOND PART OF A DOWNLINK WORD, IT MUST
#          BE CONTIGUOUS TO THE LOCATION THAT IS THE FIRST PART.
#       2. IF A LOCATION IS NOT THE FIRST WORD OF AN NDNADR IT
#          MUST BE AT A SPECIFIC NUMBER OF LOCATIONS FROM THE FIRST
#          LOCATION IN THE INSTRUCTION.
#       3. OTHER NAMES MAY BE GIVEN TO LOCATIONS IN THE DOWNLIND LISTS
#          THAT ARE NOT REFERENCED IN THE LISTS. THESE MUST NOT BE MOVED.
# THIS IS ACCOMPLISHED USING THE INSTRUCTION    CHECK=   .
# THIS INSTRUCTION GIVES A CUSS IN THE ASSEMBLY IF THE LOCATION OF THE
# FIRST TAG FIELD IS NOT EQUAL TO THE LOCATION OF THE SECOND TAG FIELD.
# THE INSTRUCTION HAS NO OTHER EFFECT ON THE ASSEMBLY OR CODE.

# THIS LIST SHOULD BE UPDATED FOR ANY CHANGES TO THE DOWNLINK LISTS.
