[antlr-interest] Diferent output when running ANTLRWorks IDE and a test rig in both Java and C# versions

[Jim Idle]

Well the hint is that your grammar is wrong.

But you need to post your grammar to get more help :-). I think, from the
way you describe your problem, that perhaps you have ambiguous lexer rules
and think that the parser influences what lexer rule is run, which it does
not.

Also, make sure you run the debugger in AntrlWorks and check any warning
messages when you generate the code.
