Hi there,

I may be missing something pretty basic, but is there a simple way to check missing value with a few statements regardless whether the variable is numeric or character ?

for example, could one make a macro like the following, both for numeric and character variable ?

%macro check(var); if &var is missing then do somthing... %mend;

Using &var=. or &var=' ', seems to give an error message for the opposite type.

Thanks in advance! Sung-il.
