推荐答案

VNAME函数会返回一个数组引用对应的变量名.

The VNAME function will return the name of the variable corresponding to an array reference.

data Have;
   input REFERENCE_DATE  
         L_CONTRACT 
         L_CONTRACT_ACTIVITY
         L_LFC
         L_CONTRACT_CO_CUSTOMER
         L_CONTRACT_OBJECT
         L_CUSTOMER
         L_CUSTOMER_RETAIL
         L_DPD
         L_GL_ACCOUNT 
         L_GL_AMOUNT
         L_EXTRA_COST 
         L_PRODUCT;
   datalines;
450 1 9 8 6 0 4 3 0 0 0 0 0
;

data want;
  length vars_with_zero $1000;
  set have;
  array L L_CONTRACT -- L_CUSTOMER_RETAIL;

  * accumulate the names of the variables that have a zero value;
  do _n_ = 1 to dim(L);
    if L(_n_) = 0 then vars_with_zero = catx(' ', vars_with_zero, vname(L(_n_)));
  end;
run;
