Hi,

I have a SAS file A which has no labels. I have another file B in which i have only 2 columns which has values (Column1: All column names in Table 1 and Column2 has all the labels) How to pull the labels which are present as a values from File B and make it as a label in File A.

Hi,

Something like:

data main;
  a=1234;
  b=23;
run;

data labels;
  var="a"; lab="A label for a"; output;
  var="b"; lab="A label for b"; output;
run;

data _null_;
  set labels end=last;
  if _n_=1 then call execute('proc datasets nolist lib=work; modify main; label ');
  call execute(cat(var,'="',strip(lab),'" '));
  if last then call execute(';quit;');
run;

Dataset1

Name	Age	Sex	Salary
Mani	22	M	10000
santhosh	23	M	12000
karan	24	M	13000
vijay	25	M	14000

Dataset 2
col	label
Name	Name of the employee
Age	age of the employee
Sex	sex of the employee
Salary	salary of the employee

Does it work in the above scenario? i wanna create a Dataset3 which is a copy of dataset 1 with all the labels

Yes, your data looks exactly like the test data I provided above.

Actually, this program does not create Dataset3. Instead, it modifies Dataset1 by adding the labels to it.

Is there any reason you would need two data sets that are identical, except for the labels?

can you alter this and tell me how to create a 3rd dataset and migrate dataset 1 and labels from dataset 2 to the new dataset?

Dataset Name 1:AE

Dataset Name 2: AE_INFO

Dataset Name 3: Test_AE

Colums in AE_INFO= name and label

Very similar tools ... the idea is to generate the proper DATA step:

data _null_;

call execute('data test_ae; set ae; label ');

do until (done);

set ae_info end=done;

call execute(col || '= "' || label || '"');

end;

call execute('; run;');

stop;

run;
