  51 1.      ABSTRACT
  52         --------
  53
  54         THE KE8-E EXTENDED MEMORY EXERCISER IS A TEST OF THE
  55         KE8-E "B MODE" INSTRUCTIONS WHICH DURING THE DEFER
  56         CYCLE USE THE WORD FOLLOWING THE INSTRUCTION TO OBTAIN
  57         THE OPERAND.  THE CAPABILITY OF EACH INSTRUCTION TO
  58         ACCESS EVERY MEMORY FIELD FROM EVERY MEMORY FIELD
  59         THROUGH NON-AUTO INDEX AND AUTO INDEX, IS TESTED.
  60
  61         THE FOLLOWING IS A LIST OF THE INSTRUCTIONS IN THE
  62         SEQUENCE THEY ARE TESTED.
  63
  64         A.  DOUBLE PRECISION ADD  (DAD)
  65

 165         E.  TYPE IN THE VALUE OF THE HIGHEST MEMORY IN THE SYSTEM
 166             FOLLOWED BY A CARRIAGE RETURN.
 167             (EG, 0 FOR 4K, 1 FOR 8K ON UP TO 7 FOR 32K)
 168             IF THE INCORRECT NUMBER WAS TYPED, TYPE RUBOUT AND THEN
 169             RETYPE THE MEMORY FIELD VALUE.
 170
 171         NOTE:
 172
 173         FOR A NORMAL PROGRAM RUN, LOAD THE PROGRAM IN FIELD 0.  SET SR TO
 174         0200 AND PRESS LOAD ADDRESS.  NOW SET SR TO 0000 AND PRESS CLEAR
 175         AND CONTINUE, AND RESPOND TO THE TELETYPE WITH THE VALUE OF THE
 176         HIGHEST FIELD FOLLOWED BY A CARRIAGE RETURN.  THE PROGRAM WILL
 177         NOW ACCESS EVERY FIELD FROM EVERY FIELD.  AT THE COMPLETION
 178         OF A COMPLETE PROGRAM PASS, "KE8-EME" WILL BE TYPED ON THE
 179         TELETYPE.
