DO we have to use NOOBS while using ID?

I guess you are talking about proc print. I think using a ID statement implies option NOOBS, since the ID variable is supposed to provide observation identification. Compare:

 

proc sort data=sashelp.class out=class; by sex name; run;

proc print data=class; by sex; run;
proc print data=class; by sex; id sex; run;
proc print data=class noobs; by sex; id sex; run;

Ummm, I was going through Chapter 4 of the SAS Cert Prep Guide. So inorder to eradicate the OBS column, we use a NOOBS. My question is, do we have to write the NOOBS in the code even when we use an ID statement? Or is it not necessary to mention the NOOBS in the code while using the ID statement?
