in the simplest case: yes, but...
Not, if you have a view, not if you have deleted obs in the dataset.
Deleted obs you might get, if your dataset is manipulated by FSP or an AF
application.
In that cases you should use other functions. I've deleted one obs in
SASUSER.CLASS. Note the following log:
41 data test;
42 rc=open("sasuser.class");
43 lobs=attrn(rc,"nlobs");
44 obs=attrn(rc,"nobs");
45 put obs= lobs=;
46 run;
obs=19 lobs=18
You see, you get 19 obs, but you can use only 18!
