The NMISS function requires numeric values and works with multiple numeric values, whereas MISSING works with only one value that can be either numeric or character. At first glance, you might be wondering if you read this correctly, because any good SAS coder worth their salt, knows that the SUM function handles missing values, well it ignores them when using the SUM function and miss=(cats(of v1-v3)^=' '); assigns a 1 to MISS if the expression cats(of v1-v3)^=' ' is true, or a 0 otherwise. sas.
