print only certain data values using _n_

I have a dataset containing 50 data values and want to print only 4th to 10th observations. How can i do this using _N_?

Thank you

Printing and _N_ are not really related concepts. The automatic variable _N_ can be used to keep track of how many times a data step has executed the implicit loop. Printing is normally done using a proc like PROC PRINT or PROC REPORT. You could make a subset of the data using a data step that references _N_ and print that. 

data to_print;
  set sashelp.class;
  if 4 <= _n_ <=10 ; 
run; 
proc print; 
run;

Since you just want one continuous range of observations you could use the FIRSTOBS= and OBS= dataset options to pick which observations you want to print, but that has nothing to do with the data step automatic variable _N_. 

proc print data=sashelp.class (firstobs=4 obs=10); 
run;

data want;
do p=4 to 10;
set sashelp.class point=p;
output;
end;
stop;
run;
