The SAS Logging Facility in the SAS Language

Example of Creating Logger and Appender Categories

The following appender and logger functions create regression and new function categories for testing a SAS program. This example assumes that filerefs that are named myPgmReg and myPgmNew have been created in the SAS program.

/* Define the destination where regression messages are written. */

if _n_ = 1 then 
   do;
      rc=log4sas_appender("myPgmRegression", "FileRefAppender", "fileref=myPgmReg");
      if rc ne 0 then do
         msg = sysmsg();
         put msg;
         ABORT;
         end;
   end;

/* Define the destination where new function messages are to be written. */

if _n_ = 1 then 
   do;
      rc=log4sas_appender("myPgmNewFunction", "FileRefAppender", "fileref=myPgmNew");
      if rc ne 0 then do
         msg = sysmsg();
         put msg;
         ABORT;
         end;
   end;

/* Create the context for logging regression messages.  */
/* Regression log events of level info or higher are written  * /
/* to the destination specified by the appender defined as myPgmRegression.  */
 
if _n_=1 then 
   do;
      rc=log4sas_logger("regression", "appender-ref=(myPgmRegression) level=info");
      if rc ne 0 then do
         msg = sysmsg();
         put msg;
         ABORT;
        end;
   end;

/* Create the context for logging new function messages.  */
/* New functionality log events of level debug or higher are written */
/* to the destination that is specified by the appender defined as myPgmNewFunction.  */
 
if _n_=1 then 
   do;
      rc=log4sas_logger("regression", "appender-ref=(myPgmNewFunction) level=debug");
      if rc ne 0 then do
         msg = sysmsg();
         put msg;
         ABORT;
         end;
   end;
