# ********** CHECK EQUALS LIST **********

# 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 DOWNLINK 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.
