I use this trick a lot. It was definitely difficult for me when I started using LowRes because you can’t return a value from a sub program, which are basically like methods. Once I figured out that formal parameters were reference type, it made writing sub programs a lot more flexible. Nice demo! :)

Thanky :)

special ability: 41% diagonal speed boost!

the distance traveled by stepping one time in two directions is step_size * SQR(2) = step_size * 1.41...

@McPepic apparently you can even send arrays to a sub

DIM ARR(9)
FOR I=0 TO UBOUND(ARR)
  READ ARR(I)
NEXT I
DATA 9,8,7,6,5,4,3,2,1,0

CALL WHATSUB(ARR)

SUB WHATSUB(ARR)
  FOR I=0 TO UBOUND(ARR)
    PRINT ARR(I)
  NEXT I
END SUB

I drove the car so fast that it went off the screen

lol I just made the typo: "v=fast"
(v means velocity in physics) ("v" is near "f" and "=" is near "backspace")

Cool array trick...

... did you also know you can do
DIM ARR(9)
inside the SUB, then use the array in the SUB.. and, like all other variables created in the SUB, it isnt seen by your main code, and gets destroyed when the SUB ends..

I actually didn't know that, makes sense now that I think about it, thank you!
