-/*
- I had to make the following changes to the basic Expr grammar to make it work with the CSharp3 target in "Java compatibility mode".
- For reference, see http://www.antlr.org/wiki/display/ANTLR3/Expression+evaluator.
-
- Add an options section to set the language to CSharp3.
-
- In the @header section, add:
- // 'member' is obsolete
- #pragma warning disable 612
- using Antlr.Runtime.JavaExtensions;
-
- In the @header section, replace:
- import java.util.HashMap;
- with:
- using HashMap = System.Collections.Generic.Dictionary<object,object>;
-
- Change all instances of "System.out" with "JSystem.@out".
-
- Change all instances of "System.err" with "JSystem.err".
-
- Change all instances of "skip()" with "Skip()".
