How to activate Preferred Alias processing using CODE-1 Plus

In order to get the Preferred Alias street returned in CODE-1 Plus (if one exists in the US Postal database), pass a Y in position 15 of the SA2OUT parameter if executing the batch driver, C1BM00.  If calling C1MATCHx, pass a Y in the P9I-PREFER field in the P9IN call area.
