another question (for me): what's the use of a dataset with no variables?
The stop-trick I use very often to get a empty dataset with a certain
variable structure. Imagine you want to continuous APPEND data, perhaps in
a macro loop and need a initial dataset to append to.
So I normally use:
data empty;
set sashelp.class;
stop;
run;
But maybe there is any use of a empty dataset without any variables (I
agree, that is kind of "more empty" than mine...)
