Example

This example opens the SAS data set MYDATA, fetches the first observation, and sets a note ID at the beginning of the data set. It uses POINT to return to the first observation, and then uses DROPNOTE to delete the note ID:

%let dsid=%sysfunc(open(mydata,i));
%let rc=%sysfunc(fetch(&dsid));
%let noteid=%sysfunc(note(&dsid));
   more macro statements
%let rc=%sysfunc(point(&dsid,&noteid));
%let rc=%sysfunc(fetch(&dsid));
%let rc=%sysfunc(dropnote(&dsid,&noteid));
