Example 1: Using VARINFMT to Obtain the Informat of the Variable NAME

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; 

Example 2: Using VARINFMT to Obtain the Informat of all the Variables in a Data Set

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;
