DROPNOTE(data-set-id |
file-id,note-id)
|
-
data-set-id | file-id
-
is a numeric variable that specifies the
identifier that was assigned when the data set or external file was opened,
generally by the OPEN function or the FOPEN function.
-
note-id
-
is a numeric value that specifies the identifier
that was assigned by the NOTE or FNOTE function.
DROPNOTE deletes a marker set by NOTE
or FNOTE. It returns a 0 if successful and 0 if not successful.
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,¬eid));
%let rc=%sysfunc(fetch(&dsid));
%let rc=%sysfunc(dropnote(&dsid,¬eid));
