how to get numeric and character  missing count using macro application

[Kurt_Bremser]

Before you engage in macro programming, start with working non-macro code.

So get rid of all the macro stuff and write a simple step which does what you do.

To get hints for this, also post the expected result for your example data.

As Kurt said no need macro at all.

data colmiss_ds ;
infile datalines truncover;
input x y z a$  b$ ;
datalines;
1   . 66      BB 
2  55  . 
3   .  .  CC  DD
4  55  . 
;
run;

proc transpose data=colmiss_ds(obs=0) out=temp;
var _all_;
run;
proc sql noprint;
select catx(' ','nmiss(',_name_,') as',_name_) into :missing separated by ',' from temp;
create table temp2 as select &missing. from colmiss_ds;
quit;
proc transpose data=temp2 out=want;
run;
