But to turn of that scrolling thing, you can either do bcall(_RunIndicOff) or just DI
bcall(_runIndicOff) will be a permanent solution that will make sure the the program never displays the run indicator until you rerun it.
DI runs the risk of interrupts being enabled which will re-enable the run indicator. (Quite a few bcalls do this, and honestly, you might need some of them (bcall(_getCSC), bcall(_clrLCDFull) (TI's mistake here), bcall(_getKey), just to name a few))
