I'm trying to figure out where the AST classes come from within your samples.
All the classes in the folder SampleBrowser\ProductSamples\SyntaxEditorSamples\QuickStart\GettingStarted04d\Ast say they were generated using the 'Actipro Language Designer tool'. I've been looking at the designer and the only thing I can figure out how to generate is the lexer.
The following thread indicates that the designer can turn out boiler plate code for the AST nodes.
So are the classes in SampleBrowser\ProductSamples\SyntaxEditorSamples\QuickStart\GettingStarted04d\Ast boiler plate classes that have been extensivley modified by hand or were they generated like this (and if so how).
