R0053 THE CODE IS A POLISH OR STORE ADDRESS CONSTANT, RESETS THE BEGINNING-OF-EQUATION INDICATOR (BIT 29 OF SWITCH)
R0055 AND RETURNS TO THE GENERAL INSTRUCTION-PROCESSING PROCEDURE. IF THE CODE IS A POLISH OPERATOR, THE SEVEN-BIT
R0057 EQUIVALENT IS PLACED IN BITS 18-24 OF HEALTH AND THE BEGINNING-OF-EQUATION INDICATOR IS EXAMINED. IF IT IS
R0059 RESET (AS IS TRUE INITIALLY), IT IS NOW SET AND 07 IS SUPPLIED AS THE SECOND OPERATOR, TO INDICATE THAT PASS 2
R0061 IS TO DECODE AN OPERATOR WORD COUNT FROM THERE. OTHERWISE, THE ADDRESS FIELD IS INTERPRETED AS FOLLOWS...
R0063 BLANK: OPERATOR 00, NUMERIC: OPERATOR 07 (ASSUME NEW EQUATION), SYMBOLIC WITH MODIFIER: OPERATION 17 (ILLEGAL

# These are opcode tables, constructed using the "M" opcode, which means 'mixed constant',
# i.e. the 'alphanumeric compressed' data type. This is a 48-bit word structured as 6 6-bit
# characters and 3 4-bit BCD digits. So, in the table entries below, each "A" operand to the
# "M" code is part of the 6-character string part, and the "B" operand supplies an octal
# number representing 0-4095.
# So, for example, applying this to the tables below, we get:
# MP 6200
# DMP 4541
# DMPR 5101
# DOT 5641
# UNIT 4231
# DMOVE 5531
# DOUBLE 7002
# AD 7000
# NDX 5040
