[Cuis-dev] question about Compiler evaluate:

[Mark Volkmann]

Thanks! That allows me to avoid writing an error message to the Transcript.
The other thing I want to do is get the error message ("x is Undeclared" in
this case) so I can display it in my UI.
Do you know how I can get that?
I don't see that in any of the instance variables associated with either
exception object.
