Declaring a variable of a given name more than once is a scripting error (always has been). You can redefine a variable OK, but you cannot re-declare it; re-declaration probably means the writer has forgotten about a variable. But the "clear" command is there if you need it, to give yourself a tabula rasa.

Yes, that would be the explanation. > Still, 'clear' is a bit too heavy as it also throws away the data... Hm. I guess we could add an option to "clear" so that the dataset is preserved while everything else is cleared.
