2.1.2.11 Miscellaneous operators
Finally, we list in the following table three miscellaneous MIX
instructions which do not fit in any of the previous subsections:
MOVE- Move MOD words from M to the location stored in rI1.
OPCODE = 7, MOD = no. of words.
NOP- No operation. OPCODE = 0, MOD = 0.
HLT- Halt. Stops instruction fetching. OPCODE = 5, MOD = 2.
The only effect of executing `NOP' is increasing the location
counter, while `HLT' usually marks program termination.
