You're going to need to say what you mean by "different". So you mean that they execute different functions (so that any two programs which produce the same output on the same input are the same), or execute different sequences of instructions, or are verbally different.
To put it concretely:
andCode:1. Input X 2. Goto 3 3. Set X = X+1 4. Stop
both produce the function X -> X+1. Are they "different"?Code:1. Input X 2. Set X = X+1 3. Goto 4 4. Stop
