----------------------------------------

             Summary: Make parsed script text available for validation errors
                 Key: SYSTEMML-1858
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1858
             Project: SystemML
          Issue Type: Improvement
          Components: Parser, Runtime
            Reporter: Deron Eriksson
            Assignee: Deron Eriksson


Currently original script text is not available for validation errors, which makes it difficult
to generate helpful validation errors (besides reporting the error and the beginning line/column
where the error is located). It would be helpful during validation error reporting to pass
the tokenized text which is already generated by antlr to classes such as statements and expressions
so that the script text can be utilized to generate more helpful error messages, which can
include information such as the statement that generated the error.
