[Vm-dev] how to print to stdout in plugin code

[Robert Withers]

I still do not know how I could print debug info to stdout, in a Squeak Plugin primitive. Hopefully I'll learn. This would be such a blessing! Please guide me!

In the meantime, I have written all GF methods as primitives, including #decode:twoS:, #runEuclideanAlgorithm adn #dividePoly:, though these 3 are not being called from the DecoderWithPlugin or GFPolyWithPlugin. The only new primitive is GFPoly>>#initializeFiled:coefficients:. Here are the numbers, with RSFEC Tests only.
