Nice. Without it, I'd probably just code:

Code: (Select All)

INPUT CarX.position, CarY.position
speedx = 1
IF CarX.position - CarY.position THEN CarX.position = CarX.position + (CarX.position - CarY.position) / ABS(CarX.position - CarY.position) * speedx
PRINT CarX.position
SLEEP
CLS
RUN

Aye, you can always code around notusing it.  Most commands are like that.  Don't like _PRINTSTRING?  Use LOCATE, PRINT, CSRLIN, and POS to duplicate its behavior.

One thing you have to admit though, comparing our two codes -- yours has a lot more to process going on under the hood.  In a game, where FPS matters, that might might a world of difference if inside some inner loop.

Agreed. I do like having keywords to handle things but I also like figuring out my own "functions" to make things I want happen. You have to admit the way I used that IF/THEN to avoid a division by zero error, in the code above, was PFC.

Pretty fine coding... Sure, let's go with that.
