            # testcase and fill frame,
            # change first three entries etc, push solve,
            # and then push report. Report allows copy and paste
            # from console to conventional texteditor.
            # For testcases, the
            # testcase number is internal to the calculator and
            # will not be printed until the report button is pushed
            # for the current result numbers.
