CLOSE(data-set-id)

Arguments

data-set-id: specifies the data set identifier that the OPEN function returns.

CLOSE returns 0 if the operation was successful, [ne] 0 if it was not successful. Close all SAS data sets as soon as they are no longer needed by the application.

Note: All data sets opened within a DATA step are closed automatically at the end of the DATA step. [cautend]

This example uses OPEN to open the SAS data set PAYROLL. If the data set opens successfully, indicated by a positive value for the variable PAYID, the example uses CLOSE to close the data set.
```
%let payid=%sysfunc(open(payroll,is));
   macro statements
%if &payid > 0 %then 
   %let rc=%sysfunc(close(&payid));
```
This example opens the SAS data set MYDATA within a DATA step. MYDATA is closed automatically at the end of the DATA step. You do not need to use CLOSE to close the file.
```
data _null_;
   dsid=open('mydata','i');
   if dsid > 0 then do;
      ...more statements...
   end;
run;
```
