;**********************MEMORY ORGANIZATION****************************
;
MOST OF THE MEMORY LOCATION IS IMPORTANT--THE FIRST TWO
;
LABELS OF THE X AND Y DATA MEMORY ARE PAIRED AND MUST
;
BE CO LOCATED (AT THE SAME ADDRESSES). IN ADDITION, STATE1
;
AND STATE2 MUST BE LOCATED ON A 0 MOD 2*NUMSTATES BOUNDARY,
;
X and Y memory for input data must be paired --GOOD LUCK.....
