Review week 3: loops and jumps

Since this week your programs run permanently. With that came the first traps that strike without an error message. The quiz checks them:

• yield and main loop: 128 instructions per tick, 0.5 seconds per tick, and a chip that runs off the end stops for good.
• sleep: waits seconds, makes the chip deaf and never belongs on line 0.
• Labels and jumps: labels stand alone on their line, j always jumps, beq and co. only when the condition holds.
• Jumps against zero: bltz, bgtz, blez, bgez – build the difference first, then jump.
• Counters: one per tick, reset by button or mod.

You pass from 60 %.
