The code for handling character constants in datalists in ncgen has some problems. 1. It failed on large constants 2. It did not handle e.g. var = 'a', 'b', ... in the same way that ncgen3 did. 3. The code for generate.c and genchar.c needed some refactoring to make it a little simpler (but not simple).
