The possibility of no variables is interesting--I am not sure

worth either (a) reviewing commands to make sure they can handle

variable. The latter probably makes more sense, seeing as it's
somewhat meaningless to attempt data analysis when there are no
variables.
OK. I've committed this patch with option b. We may want to reconsider this later. I can envisage some complex syntax examples, where the programmer might not know how many variables a dictionary has. Some commands I think might be usefull in such a state, for instance DISPLAY DICTIONARY.
