Next: , Previous: , Up: MIX instruction set   [Contents][Index] Miscellaneous operators

Finally, we list in the following table three miscellaneous MIX instructions which do not fit in any of the previous subsections:


Move MOD words from M to the location stored in rI1. OPCODE = 7, MOD = no. of words.


No operation. OPCODE = 0, MOD = 0.


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.
