Jen,

Should all negative values be set to missing?  If so, then you
can use an array to loop over all of the numeric variables and
set any value which you find to be negative to missing.

Code which would do this is

data mydata;
  set mydata;
  array _numvarss_ {*} _numeric_;
  do i=1 to dim(_numvars_};
    if _numvars_{i}<0 then _numvars_{i}=.
  end;
run;


HTH,

Dale
