TRANWRD修復合併錯誤？

Question

我最近將兩個數據集合併成了一個非常簡單的Merge聲明。我正在使用ACS數據集和人口普查人口數據集。我需要後者的國旗在前者。當我合併的地方變量（鎮/縣，州）沒有去重複，因爲一個數據集的使用狀態的縮寫，而其他使用完整拼寫：

Obs GeoID   GeoName 
    1 .   Abbeville County, SC  
    2 45001  Abbeville County, South Carolina 

我需要改變GeoName爲Obs1使它等於Obs2

請問index函數是否工作？或者我需要TRANWRD函數？謝謝。

解決：

data _null_; 
length geoName $100; 
GeoName_C = scan(GeoName,1,','); 
GeoName_S = scan(GeoName,-1,','); *-1 scans from the right in case you could have commas in the city - check for this and adjust GeoName_C to include them if it is possible; 
GeoName_S_F = stnamel(strip(GeoName_S)); 
GeoName = catx(',',GeoName_C,GeoName_S_F); 
put _all_; 
run; 

Answer 1

我會做的是從國家獨立的城市，使用SAS的內置功能stnamel的縮寫轉換爲全名。

data _null_; 
length geoName $100; 
GeoName='Abbeville Road, SC'; 
GeoName_C = scan(GeoName,1,','); 
GeoName_S = scan(GeoName,-1,','); *-1 scans from the right in case you could have commas in the city - check for this and adjust GeoName_C to include them if it is possible; 
GeoName_S_F = stnamel(strip(GeoName_S)); 
GeoName = catx(',',GeoName_C,GeoName_S_F); 
put _all_; 
run;
