okay, so i built this macro a while ago. it was in a different thread in this forum. i used it in the past and it worked however i am getting weird, kind of unidentified errors... %macro VarExist(ds,var);
%local rc dsid result resx;
%let dsid = %sysfunc(open(&ds));
%let resx = %sysfunc(varnum(&dsid,&var));
%let rc = %sysfunc(close(&dsid));
%if &resx > 0 %then %do;
%let result = 1;
%put NOTE: Var &var exists in &ds;
%end;
%else %do;
%let result = 0;
%put NOTE: Var &var not exists in &ds;
data &dsid;
&var='UNK';
set &dsid;
run;
%end;
%mend VarExist;
%VarExist(TABLE_01,FIELD_01); however, like i said, when i run this i get this error... 93

also, should i insert a line to close the table or does it just do that because i have the rc line in there?
