/* SAS 9 introduces the PUTLOG statement to write messages to the SAS log */
/* while writing to a flat file. In Example 1 below, only NAME would be */
/* written to the external file, while the message "Encountered first male" */
/* would be written to the SAS log. */
/* */
/* If you are running prior to SAS 9, you can get the same result using */
/* macro logic. See the alternative technique illustrated in Example 2 below. */
/* Example 1 - PUTLOG */
