You can change it? Read the instructions. The routine just checks if the variable is 0, if it is not 0, then you cannot run away. The reason why I mention 0x1 is because the way Toggle Capture is set up, if the value is 0x1 then you can't catch the Pokemon. Because I've made the code use the same variable as that routine, if that value is 0x1 you CANNOT run or CAPTURE the pokemon. If you make the value 0x2, you cannot run, but you CAN capture.
