 ; READ EACH RECORD FROM 176.111 AND USE THE VUID TO LOOK UP THE RXNORM
 ; CODE FROM 176.001 (RXNORM CONCEPTS)
 ; POPULATE ALL FIELDS IN 176.112 AND SET "NEW" TO "Y" IF 176.111 DOES NOT
 ; ALREADY HAVE AN RXNORM CODE.

 ; AND COMPARE THE RXNORM TEXT FIELD WITH THE VUID TEXT FIELD, SETTING THE
 ; "DIFFERENT TEXT" FIELD TO "Y" IF THERE ARE DIFFERENCES
