The incorrect number of arguments misleading error is a known problem that I haven't had time to fix yet.

In TypeGen.cs, line 114: <snippet> MethodBuilder mb = myType.DefineMethod(name, attrs, retType, paramTypes); return new CodeGen(this, mb, mb.GetILGenerator()); </snippet> In that snippet above, although the paramTypes is a Type[] of length 1 (created using makeArray() in Constant.cs), somehow the MethodBuilder instance that DefineMethod() returns has 0 argument. In the case of abs() above, the property Signature prints: {Name: abs Attributes: 22 Method Signature: Length: 4 Arguments: 0 Signature: 0 0 28 28 0 } I've tried it with .NET Framework 1.1 (just the part about creating the MethodBuilder) and the result is: Length: 4 Arguments: 1 Signature: 0 1 28 28 0 Cheers, Ray __________________________________________________ Do You Yahoo!?
