在SAS中使用do循環創建新變量

我有一個SAS程序，它有一個基準年和五個預測年。所有的預測年份都有相同的計算結果，但只是使用上一年的數據作爲計算基準年。我想避免複製數據5次，只是改變我的變量名稱的後綴。只有一個預測年份並且有一個do循環或一個數組來更改變量名稱的後綴會很好。這是我更新的代碼根據您輸入的：在SAS中使用do循環創建新變量

*Start macro loop - takes two parameters, the first year of the dataset to be created and the last year; 
%macro loop(year_start, year_end); 

    *loop over years; 

    %do year=&year_start %to &year_end; 
    *create macro variable for previous years; 
    %let prev_year=%eval(&year_start-1);

，如果你想不同的數據集，你需要一個宏循環。如果你想有一個單一的數據集，你

*Start macro loop - takes two parameters, the first year of the dataset to be created and the last year; 
options mprint symbolgen; 
%macro loop(year_start, year_end); 
    *loop over years; 
    %do year=&year_start %to &year_end; 

    *create macro variable for previous years; 
    %let prev_year=%eval(&year_start-1); 

    DATA SchoolAid_FY&year_start.; 
    Set work.SchoolAid_FY&prev_year.; 

    * COST PER PUPIL AMOUNTS;      
    L201_FY&start_year.= L203_FY&prev_year.;         
    L202_FY&start_year.= Round(SCPP*SPG_FY&prev_year.,1);   
    L203_FY&start_year.= Sum(L201_FY&prev_year.,L202_FY&prev_year.); 

    *Rest of your code; 

    Run; 
    %end; 
    *end of do loop; 

    %mend; 
    *end of macro;

然後，你必須調用宏，因此，例如，如果你想從15到20使用year_start = 15，year_end = 20。

%loop(year_start=15, year_end=20);

非常感謝您的幫助！我幾乎有這個工作，但我堅持我怎麼稱呼maco。我在哪裏放：％循環（year_start = 15，year_end = 20）;我已經在％宏循環區域和代碼的末尾嘗試過了。 – user3353530

宏後的任何地方 – Reeza

我仍然沒有得到任何產出。我想知道我是否在做其他的錯誤。這是我的代碼的結束：運行; ％end; *循環結束; ％修復; *宏結束; ％loop（year_start = 18，year_end = 20）; – user3353530
