Depends on the environment. Are any tables open? If so, could be a field value (though naming a field 'a' would be a very poor choice). In fact, if that's the case, you could have an infinite loop. Or c could be a field and thus the loop have a different termination.

No, unless you consider not using mdot a trick.
