I agree that the actual output of your example is wacky and unexpected, but what I'm trying to get you say is what YOU think should happen. The examples that you pasted in your previous post did not and could not do what you said you wanted them to do, so I don't quite understand what the bug is. Put more simply, if you generate wacky command lines you should not be surprised when they produce wacky results. :) Doug On two occasions I have been asked [by members of Parliament!], "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?"
