23 ; READ EACH RECORD FROM 176.111 AND USE THE VUID TO LOOK UP THE RXNORM
24 ; CODE FROM 176.001 (RXNORM CONCEPTS)
25 ; POPULATE ALL FIELDS IN 176.112 AND SET "NEW" TO "Y" IF 176.111 DOES NOT
26 ; ALREADY HAVE AN RXNORM CODE.
27 ; ADD THE RXNORM TEXT FIELD TO EVERY RECORD (NOT PRESENT IN 176.111)
28 ; AND COMPARE THE RXNORM TEXT FIELD WITH THE VUID TEXT FIELD, SETTING THE
29 ; "DIFFERENT TEXT" FIELD TO "Y" IF THERE ARE DIFFERENCES
