# 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 SIE 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 96
#				IT MAY BE SHARED WITHANY 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.
