What command can be used to check if a list exists (Archived preferably) without giving the undefined error?
Thanks, I didnt know what command it was, or even if there was one.
Oh ya, changed the graphscreen page, there are 95 by 63 editable pixels. It used to say that their were 94 by 62, I'm guessing it was posted as this because the Pxl_On command and such believe the top left pixel to be -1,-1. I probably missed some areas where this could be changed.
Well, it's easy to forget the 0 pixel … it just sits there doing nothing :D
Well, it's all relative — relative to the pixel next to it :D
There's another way to check -and only check- whether a list exists:
:If not(dim(L₁ :Then (input code) :End
