what is use of  " ??best. "  format? How it will work?

The double-question mark supresses the printing of invalid data notes in the log, and prevents SAS from setting _ERROR_ to equal 1 when invalid data is encountered.

Since the reply I gave was helpful to you, please do something helpful for the rest of us. From now on, make the subject line a short but meaningful description of your SAS problem. Phrases like "Doubt" "Need Help" "Don't Understand" are not acceptable as they don't help anyone find topics of interest.
