Re: [Gm2] mea culpa, testcase9 is good, but testcase8??

[Andreas Fischlin]

I do not understand what this testcase8 should be good for. The test program 
behaves erratically and for good reasons. Why do you wish to compare two 
variables which were never assigned any value? This simply makes no sense to 
me. Do you wish to test whether the linking/loader does assign for you any 
uninited variable? If yes, why not writing a simpler program such as this one:

MODULE TestCase8;

        VAR x,y: INTEGER;

BEGIN 
  IF x <> y THEN (* FAIL *) END;
  IF NOT x = y THEN (* PASS *) END;
END TestCase8.

Can anyone clarify? It still does not make much sense.

Regards,
Andreas
