==== Instruction Set ====

^ Code ^ Name ^ Description	^
| 0 | HLT	 	| Stop (Little Man has a rest).	 |
| 1 | ADD	 	| Add the contents of the memory address to the Accumulator	 |
| 2 | SUB	 	| Subtract the contents of the memory address from the Accumulator	 |
| 3 | STA or STO	| Store the Accumulator value at the memory address given.	 |
| 4 |  	 	    | This code is unused and gives an error.	 |
| 5 | LDA	 	| Load the contents of the memory address given	into the Accumulator. |
| 6 | BRA	 	| Branch - use the address given as the address of the next instruction	 |
| 7 | BRZ	 	| Branch to the address given if the Accumulator is zero	 |
| 8 | BRP	 	| Branch to the address given if the Accumulator is zero or positive	 |
| 9 | INP or OUT	| Input or Output. Copy Input to Accumulator if address is 1, copy Accumulator to Output if address is 2.	 |
| 9 | OTC	 	| Output Accumulator as a character if address is 22. (Non-standard instruction)	 |
| 9	| DAT	 	| Store the given number into memory.|
