Arguments

Examples

This example obtains the informat of the variable NAME in the SAS data set MYDATA.

%let dsid=%sysfunc(open(mydata,i));
%if &dsid %then
   %do;
      %let fmt=%sysfunc(varinfmt(&dsid,
                        %sysfunc(varnum
                           (&dsid,NAME))));
      %let rc=%sysfunc(close(&dsid));
   %end;

This example creates a data set that contains the name and informat of the variables in MYDATA.

data vars;
   length name $ 8 informat $ 10 ;
   drop dsid i num rc;
   dsid=open("mydata","i");
   num=attrn(dsid,"nvars");
   do i=1 to num;
      name=varname(dsid,i);
      informat=varinfmt(dsid,i);
      output;
   end;
   rc=close(dsid);
run;
