So the PRINT, PLOT, DRAW and CIRCLE will then work directly in Radastan mode. I only see one weak point: Backward compatibility. If it comes to the point, where it falls back into normal Spectrum Mode because the Hardware does not support Radastan. This means, we must produce two binarys to support ZX UNO advanced moda and Sinclair ZX Spectrum. But no problem, as the Radastan routines can be added as SUB/FUNCTION.
