SyntaxCheck.dss demonstrates the general approach to creating a syntax checker with Data Splitter.   Syntactically correct input follows the "green" path.   Errors are trapped by the red links when the green path can't be followed.   In general, the "red" links will connect to "anything" nodes, and must have the highest link number (i.e. be the last link tried).
