There's not much you can optimize in this code because every record has to be processed. The speed of standardize() program would have major impact on the overall speed. It's not clear how that program returns values into stname, stno, predir and secadr variables.

SELECT mytable
IF RECCOUNT() > 0
	SCAN
		standardize(mytable.address)
		REPLACE streetname WITH stname, ;
                        streetno WITH stno, ;
                        predirectional WITH predir, ;
                        secondaryaddr WITH secadr
	ENDSCAN
