Brian, that's certainly the 'most obvious way' - but unless you really want/need to (or are using this 'modified dataset' repeatedly), there is no actual need to create your dataset 'temp' - with just a very slight addition to your code, you could make it a 'view' of the original dataset:

data temp / view = temp ; set test; array test _numeric_; do i=1 to dim(test); if test(i) in (888,999) then test(i) = .; end; run ; proc print data = temp ; run; proc means data=temp; run;

Kind Regards
