Is it a compiler error or incorrect documentation?
p.s.
I had plans to identify the device by screen size in millimeters.
It was a fiasco.

Do I understand correctly that
#PB_Unit_Point
#PB_Unit_Inch
#PB_Unit_Millimeter
in SpiderBasic is not supported and you need to correct the documentation?

Or is this a bug?

Am I the only one who cares about this?

[plouf]

welll vector drawing is not very popular , but we all want this fixed because sometime will needed

seems like a bug since Debug VectorUnit(), return correct unit is being set each time
