Ron... Not so fast... I see it as a half solution to the problem. Ussually when you want to know the number of obs in a data set it is a decision point in a macro. The &SysNobs is only valid if it is the last data set sas used. What we really need imho.. is a function that retrieves it for us possibly with a few options to specify logically deleted obs or not.
