help with macro

[deanj2k1]

data Subjects;
set Subjects;
%let missvaluesw=%NMISS(of wheeze);
%let missvaluesc=%NMISS(of cough);
run;

returns the error:
Warning: apparant invocation of macro NMISS not resolved

does anyone know what the problem is?

There is no macro function NMISS. You could try to run that function in a %SYSFUNC() macro function. I don't think that you will get the results you want, but it may help you.
