Why would you want to do this, anyway? SAS works best when you
keep the large data sets intact.
Instead, mark the 41-record blocks with an identifier so each block
has a different value, and you can use by-processing. Or WHERE
clauses. Or whatever you need. Try this:
data new/view=new;
set YourOldData;
block = ceil(_n_/41);
run;
