When you say blank, do you mean a dataset with all missing values?

If it has 10 observations, it sure won't be "blank". In terms of datasets, I would reserve that word for a dataset that has only structure, but no observations.

If you just want 10 observations of missing variables, write a data step that has a format statement for your variables and does 10 outputs.

Here is one way:

data want;
  format a b c $2.;
  format d e 8.;
  do _n_=1 to 10;
    output;
  end;
run;

Seriously though, why are you creating blank datasets.  This not only creates this work (and question) but also creates the other question of how to remove them per you other post.  What is it your trying to do, there will be far better methods than creating loads of blank datasets and then deleting them, thats just a waste of processing power.

/* you can use the below simple code as well */

 


data z;
input id1$ id2$ id3$ id4$ id5$;
cards;
a b c d e
a b c d e
a b c d e
a b c d e
a b c d e
a b c d e
a b c d e
a b c d e
a b c d e
a b c d e
;
run;

 

data blank;
set z;

id1="";
id2="";
id3="";
id4="";
id5="";
run;
