         URL$SHORT.LINK = OCONV(S241<S241$LINK.PAGAMENTO>,"TSGVAR256;X;;18")
         URL$SHORT.SITUACAO = OCONV(S241<S241$LINK.PAGAMENTO>,"TSGVAR256;X;;13")
         LINK.SITUACOES    = ""
         LINK.SITUACOES<1> = " APRE"
         LINK.SITUACOES<2> = " ABERTOPAGORECUSADOEXPIRADO"
         LOCATE(URL$SHORT.SITUACAO,LINK.SITUACOES,1;POS$LINK) ELSE POS$LINK = 1
         IF URL$SHORT.LINK EQ "" THEN URL$SHORT.LINK = "NAO GERADO"
         PRINT @(45,10):URL$SHORT.LINK
         PRINT @(45,11):LINK.SITUACOES<2,POS$LINK>
