[程式] 請問SAS的大量資料垂直合併。
因為需要垂直合併大量資料，
請問各位先進以下語法是哪裡寫錯。
Libname DefDD "G:\Deficiency\ICD\DefDD";
%macro DefDD1klmn;
%do klmn=1996 %to 2011;
%do i= 1 %to 9
proc data=DefDD.defr0&i._dd&klmn.;
out = DefDD.DefDD1&klmn.;
replace;
quit;
proc append base=final data=DefDD.DefDD1&klmn.;
quit;
%end;
%end;
%mend;
%DefDD1klmn;
Log顯示出：
WARNING: Apparent symbolic reference I not resolved.
ERROR: A character operand was found in the %EVAL function or %IF condition where a numeric operand is required. The
condition was: 9 proc import datafile=DefDD.defr0&i._dd&klmn.
ERROR: The %TO value of the %DO I loop is invalid.
ERROR: The macro DEFDD1KLMN will stop executing.
請問是哪裡寫錯？？感恩。
