Returns the label assigned to a SAS data set variable
Category: SAS File I/O
VARLABEL ( data-set-id , var-num )
data-set-id
specifies the data set identifier that the OPEN function returns.
var-num
specifies the number of the variable's position in the SAS data set.
Tip: This number is next to the variable in the list that is produced by the CONTENTS procedure.
Tip: The VARNUM function returns this number.
If no label has been assigned to the variable, a blank string is returned.
VLABEL returns the label that is associated with the given variable.
This example obtains the label of the variable NAME in the SAS data set MYDATA.
%let dsid=%sysfunc(open(mydata,i)); %if &dsid %then %do; %let fmt=%sysfunc(varlabel(&dsid, %sysfunc(varnum (&dsid,NAME)))); %let rc=%sysfunc(close(&dsid)); %end;
