How do I loop over _char_ data SAS

Question

%macro var_in_list(z);
proc contents data=&z. noprint out=cont(keep= name);
run;
proc sql noprint;                              
 select Name  into :VarList separated by ' '
 from cont;
quit;
proc sql noprint;
select count(*) into :count from cont; quit;
%put &count.;
%put &VarList.;
%let a=;

%let finish=%sysfunc(countw(&VarList));
  %do i = 1 %to &finish;
  %put var_&i= %scan(&varlist., &i, " ");
    %ordinal(var_&i);
  %end;

/*%do j=1 %to &finish;*/
/*  %ordinal(a_:);*/
/*%end;*/

%mend var_in_list;

&varlist.=WOE_ASSET_TYPE WOE_CURRENT_ASSETS WOE_CURRENT_LIABILITIES_1 WOE_DEPRECIATION_1 
            WOE_DebtAmount WOE_Delta_TL WOE_Delta_TS WOE_Delta_interest WOE_Delta_npbt WOE_Delta_taxes WOE_EBITDA_COVERAGE WOE_EFA 
            WOE_EPP WOE_IsCodebtor WOE_NACE WOE_OutstandingAmount WOE_PPLTL WOE_PPTA WOE_PRODUCT WOE_P_price WOE_TEENOR WOE_T_L1 
            WOE_max_LD_1 WOE_max_LD_2 WOE_max_LD_3 WOE_max_LD_4 WOE_max_LD_5 WOE_max_LD_6 WOE_max_LD_7 WOE_max_LD_8 WOE_max_LD_9 
            WOE_max_LD_10 WOE_max_LD_12 delnum percbad tot

I want:

%ordinal(WOE_ASSET_TYPE); %ordinal(WOE_CURRENT_ASSETS); etc.

I'm just trying to automate a simple process due to lazyness.

You are referencing a macro variable you never create. You don't really need any macro varaiable. You can just pass the results of the scan to the macro call.

%do i = 1 %to &finish;
  %ordinal(%scan(&varlist., &i, %str( ) ));
%end;

Note your call to %SCAN() is setting both space and double quote as the delimiter characters. It will not have any impact unless some of the variable names actually include double quote characters.
