I suppose I found a way myself combining

-sum- to check whether the minimum is 0 and the maximum is 1

and

-distinct- (if installed) to check whether there are only two distinct values.

Is there a programmer's command to find out whether a variable is a dummy variable ?
I need it because all dummy variables in my program are to be treated differently from continuous variables.

Thanks for any comments,
Thomas
