CLOSE Function

Closes a SAS data set

Category: SAS File I/O

Syntax

CLOSE ( data-set-id )

Arguments

data-set-id

• specifies the data set identifier that the OPEN function returns.

Details

CLOSE returns 0 if the operation was successful, ‰  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.

Examples

• 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;
