Cracking the 500 Language Problem

Ralf Lämmel and Chris Verhoef

We explain what the 500 language problem is, why it is a relevant problem, and why solutions are needed. We propose a solution, which is rapid development of renovation parsers by stealing grammars. We illustrate this by applying this approach to two non-trivial but representative languages: a proprietary real-time language from the telecommunications industry, and a well-known dialect of the most popular language in the world: IBM's VS Cobol II. We share the lessons we learned with our efforts to solve the 500 language problem.
