By the way, as a challenge, try how you can program an "If" statement in Flipjump.

I wondered this as well.

Thinking about it, if all you have is "invert some (N>1?) bits somewhere and jump to somewhere" .. I could see maybe it might work if you use self modifying code and there's really a 2nd instruction that is a no-op? Seems like it might work more like a cellular automata?

Of course, one could just go look at the documentation, but where's the fun in that?

  • You don't need a no-op; you can always just flip a bit you don't care about (e.g. reserve a word just for that) and then jump to next instruction.

Would like to know the answer. Thx.

  • Alright - https://github.com/tomhea/flip-jump/wiki/Learn-FlipJump#memo...

    • To the best I now understand, the jump address is allowed to be an expression using a specified bit variable. That would mean that the language has means to compile an expression for evaluation at the run time. If I am understanding correctly, then the power of flip jump is coming from those expressions, not the base flipjump instruction itself.

      If I haven't understood this right, then I still do not follow how if statement works with flipjump.
