My code is as below:  %let &_DOMAIN = 'S' ; DATA _NULL_;   IF &_DOMAIN = 'S' THEN DO;     %LET _DTLTRAD  = "CAPP_1Q18_ACAS_Detail_R00_20171101_Primary";  %LET _DTLTRAD1  = "CAPP_1Q18_ACAS_Detail_R00_20171101_Secondary";  END;      ELSE IF &_DOMAIN = 'A' THEN DO;     IF &_state IN ('CO','CT','DE','MA','ME','MN','NH','OR','UT','VT','VA') THEN DO;     %LET _DTLTRAD  =  "&ST1._APCD_Y&YR.M&MN._eRCE_STND_DET_PRIME.txt" ;     %LET _DTLTRAD1  = "&ST1._APCD_Y&YR.M&MN._eRCE_STND_DET.txt" ;     END;     ELSE IF &_state IN ('AR','KS','WA') THEN DO;     %LET _DTLTRAD  =  "&ST1._APCD_Y&YR.Q&QT._eRCE_STND_DET_PRIME.txt" ;     %LET _DTLTRAD1  = "&ST1._APCD_Y&YR.Q&QT._eRCE_STND_DET.txt" ;    END;   END;   PUT &_DTLTRAD;   PUT &_DTLTRAD1;   RUN;   Result of this is:   AR_APCD_Y17Q01_eRCE_STND_DET_PRIME.txt AR_APCD_Y17Q01_eRCE_STND_DET.txt   Where it should be:   CAPP_1Q18_ACAS_Detail_R00_20171101_Primary CAPP_1Q18_ACAS_Detail_R00_20171101_Secondary   Can you help? I cant understand why it is going in second loop. Thanks in advance ... View more
