Possible CE Bug?

UBERhelp1 03 Dec 2019 17:13

I have a program where I output a box of gray towards the bottom of the graph screen:

ClrDraw
BackgroundOn WHITE
Vertical 0,WHITE
-30ΔY→Y
Repeat Y=Ymin
Horizontal Y, MEDGRAY
Y-2ΔY→Y
End

You might notice I have a random "Vertical 0, WHITE" in there that serves no purpose. However, without it, the program resets Y to zero after the Repeat loop runs for the first time, so that the box of color goes from the center of the screen to the bottom. Seems like a bug.

Yes, it is a bug on OS 5.4. I tried out and experimented with your code, and it displays like you don't want it to w/o Vertical 0,WHITE.

It's not a bug. This is because the OS uses the Y (and sometimes X and Theta) variables when using the graphscreen. Avoid using these variables in your programs.
