# Assembly language for subleq machine.

Subleq machine is a one instruction set computer (OISC). The instruction subleq works as follows.

```

subleq A B C :-  mem[B] = mem[B] - mem[A]

                 if mem[B] <= 0:

                     program_counter = C

```

## Special instructions

1. If B is -1 then mem[A] is printed as a character and program counter is set to C.

2. if program_counter is -1 then execution stops.
